The four to five side spines reach a length of 4 to 5 millimeters The flowers reach a length of 20 to 25 centimeters Their pericarpel and the corolla tube are virtually without wool, but filled with large scurf’s. The spherical, redfruits are edible and strongly tuberculate. They have diameters of 4 to 4.5 centimetres.

A cluster of pollen-bearing male cones at Mount San Antonio Suillus tomentosus, a fungus, produces specialized structures called tuberculate ectomycorrhizae with the roots of lodgepole pine (Pinus contorta var. latifolia). These structures have been shown to be the location of concentrations of nitrogen-fixing bacteria which contribute a significant amount of nitrogen to tree growth and allow the pines to colonize nutrient- poor sites.

The third and fourth fingers are tipped with enlarged ball or disc-like pads, the other digits have much smaller discs, the feet smaller than the hands. The discs of the hands are equal to or wider than the tubercles. The skin of the back can be either smooth with some warts, but is never tuberculate. Adult males have nuptial pads and vocal slits.

Dendropsophus joannae is a species of frogs in the family Hylidae. It is known from the Pando Department, northern Bolivia (where its type locality is), western Brazil (Acre and Amazonas states), and Madre de Dios Region of southeastern Peru. It is similar to Dendropsophus leali but is smaller, has a shorter snout, more protuberant eyes, and more tuberculate dorsal skin. The specific name joannae honors Mrs.

The subcircular operculum is somewhat concave within. Its outer surface is closely tuberculate and whitish.G.W. Tryon (1888), Manual of Conchology X; Academy of Natural Sciences, Philadelphia Turbo marmoratus is the host of the ectoparasitic copepod Anthessius isamusi Uyeno & Nagasawa, 2012 The shell of marbled turbans is used as a source of nacre. The large opercula of Turbo marmoratus have been sold as paperweights or door stops.

The smooth shel lshows distant revolving striae, the upper ones nearly obsolete. The spire is concavely depressed, with a raised pink apex and is somewhat tuberculate. Its color is yellowish with a band of irregular white blotches dotted and shaded with chestnut in the center, and smaller ones at the upper part and base.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.

Shloenbachiidae is a family of hoplitoid ammonoid cephalopds mostly from the lower Upper Cretaceous, (U Albian - Cenomanian). Shloenbachiidae can be recognized by their usually keel bearing, irregularly ribbed and tuberculate shells that vary from evolute to rather involute and compressed to inflated. Tubercles are concentrated on the umbilical and ventrolateral shoulders. The suture, similar in all members, is ammonitic; raggedy with spikey subdivided lobes and irregularly subdivided saddles.

Species of the genus Niceforonia are small frogs measuring up to in snout–vent length. The head is narrower than the body and the tympanic membrane is differentiated, but in some species only the tympanic annulus is visible under skin. The dorsum is smooth to weakly tuberculate, whereas the venter is smooth or areolate. The terminal discs on digits are not expanded but usually bear weak circumferential grooves.

Enekbatus clavifolius is a shrub endemic to Western Australia. The spreading shrub typically grows to a height of and blooms between July and September producing pink-purple flowers. The species shares features with Enekbatus cryptandroides, both of which have to have ten stamens that are oppositely arranged to the sepals and petals. They also have tuberculate and usually often fruit containing many smooth seeds partly covered by an adherent scurfy layer.

Enekbatus cryptandroides is a shrub endemic to Western Australia. The dense shrub typically grows to a height of and blooms between September and October producing pink-white flowers. The species shares features with Enekbatus clavifolius, both of which have to have ten stamens that are oppositely arranged to the sepals and petals. They also have tuberculate and usually often fruit containing many smooth seeds partly covered by an adherent scurfy layer.

The suborbital tooth is strong and sharply pointed, visible in dorsal view; the suborbital margin is evenly curved and tuberculate. The cheliped merus has a sharp spine subdistally and with a distal dorsal spine; carpus roughened dorsally, with distal outer spine, denticulate anterior margin, and strong and slender distal spine. Its right chela has a distal angled projection. The meri of its walking legs have a distinct distal dorsal spine.

They are marked by strong, vertical, axial ribs, of which 18 occur upon the first, 22 upon the second, 20 upon the third, 22 upon the fourth and penultimate turn. In addition to the axial ribs the whorls are marked by four slender, spiral cords which do not render the ribs tuberculate. The spaces between the cords and the ribs are deep round pits. The sutures are channeled.

Fruit bodies of Lopharia fungi are crust like, to effused- reflexed (like a crust with the edges curled out to form caps). The sterile portion of the crust surface is tomentose, while the spore-bearing surface (the hymenium) is smooth or tuberculate. The colour ranges from greyish-white to cream to pale yellowish. Lopharia has a dimitic hyphal system, meaning that it contains both generative and skeletal hyphae.

Flowers: Lateral sepals 3.1 - 5.3 mm long with distinct petals of 3.6 - 5.7mm. The petals lip is scrotiform (pouch shaped) 2.5 - 4.2 x 2.2 - 3.5mm in size with the apex reflexed (bent outwards) with a slightly tuberculate (bumpy/rough) outer surface. The inner surface is smoother but has thicker veins throughout. The anthers are inflexed (bent inwards) within a cup-shaped clinandrium (an orchid structure beneath the anther).

It has prominent labial folds, long digits, and smooth skin, which differs from the tuberculate skin typical of newts. The head, back, and tail of P. brevipes range in color from light brown to a dark chocolate brown and are covered in dark spots. The underbelly color varies considerably, from a very light brown to a solid black. Breeding males may develop bluish-white spots on the tail.

Gasteria armstrongii, considered by many authorities to be a variety of Gasteria nitida which simply keeps its juvenile form, into adulthood A smaller plant, Gasteria armstrongii, which occurs just to the west on the banks of the Gamtoos river, is often considered to be a subspecies of G.nitida, which never leaves its juvenile phase (a possible case of neoteny). The armstrongii plant has rough, tuberculate, recurved, purely distichous leaves, and a solitary unbranched inflorescence.

Antrodiella tuberculata is a species of fungus in the family Steccherinaceae. Found in Mexico, it was described as new to science in 2001 by mycologists Leif Ryvarden and Gastón Guzmán. The type collection was made in Totutla (Veracruz), where it was found fruiting on a dead coniferous log. Characteristics of the fungus include its densely tuberculate cap, and spores that are small (measuring 3–3.5 by 2–2.5 μm) and roughly spherical.

Simard, S.W.; Beiler, K.J.; Bingham, M.A.; Deslippe, J.R.; Philip, L.J. and Teste, F.P. 2012. "Mycorrhizal networks: Mechanisms, ecology and modeling". "Fungal Biology Review" 26: 39-60 Suillus tomentosus, a basidiomycete fungus, produces specialized structures known as tuberculate ectomycorrhizae with its plant host lodgepole pine (Pinus contorta var. latifolia). These structures have been shown to host nitrogen fixing bacteria which contribute a significant amount of nitrogen and allow the pines to colonize nutrient-poor sites.

Tympanum is absent, and the supratympanic fold is weak. The fingers and toes have no webbing nor lateral fringes; the digital tips are slightly swollen. Skin of the dorsum is tuberculate; dorsolateral folds are present. Coloration is variable; dorsal and lateral ground coloration vary in various shades of reds, browns, and greens (cinnamon, grayish horn color, pale pinkish buff, light russet vinaceous, robin rufous, brick red, brussels brown, brownish olive, and peacock green).

The shoulder bears the first of the four stronger tuberculate spiral ridges. Connections that join the tubercles in the spiral series are a little more strongly developed than those that link them vertically—the spaces enclosed between them being deep squarish pits. The tubercles are very prominent and rounded; there are about 16 upon the second, 20 upon the third, and 26 upon the penultimate turn. The axial series slants retractively from the posterior suture.

Reticulidia halgerda grows to a maximum length of 7.0 cm. This species is different externally and internally from species in the Phyllidia and Phyllidiopsis genera, both of which also have yellow coloration and tuberculate ridges. Reticulidia halgerda does not have spiculose tubercles but instead has reticulate ridges on the notum that are smooth. Phyllidia ocellata, Phyllidia tula, Phyllidia varicosa, and Phyllidia coelestis all have a different foregut as well as tubercles capped with yellow coloration.

The five whorls of the teleoconch are moderately rounded, strongly contracted at the sutures, and somewhat shouldered at the summits. They are marked by strong, tuberculated axial ribs and four spiral cords almost as strong as the ribs between the sutures which renders their junction with the ribs tuberculate. Of the ribs which are slightly protractive, 17 appear upon the first to third and 19 upon the penultimate whorl. The sutures are strongly channeled.

In fruit, the orbicular to broadly elliptic bracteoles enlarge up to 7.5-14 × 6–12 mm and form a flattened wing-like structure. They become bright pink to red-tinged, yellowish green, or whitish, making the plant one of the more colorful shrubs in the springtime habitat. The enclosed fruit (utricle) is brown, 1.5–2 mm, with free pericarp. The vertically orientated seed is compressed-lenticular and has a brown, tuberculate seed coat.

The style is short with an enlarged base and purple to white in color. The capsule, which is a kind of dry fruit produced by many flowering plants, is globose and sometimes tuberculate. The plant was found to reproduce mainly by vegetative propagation in the field. It has been observed that Paris polyphylla seeds produce primary root about seven months after sowing and then leaves about four months later in the second year.

P. hodgarti is diagnosed by having no post-labial groove (unlike other members of Glyptosternina), gill openings not extending to the underside, homodont dentition, pointed teeth in both jaws, tooth patches joined into a crescent-shaped band in upper jaw, and 13-16 branched pectoral fin rays. This fish species has a depressed head. The body is elongate, and it is depressed anteriorly. The skin is smooth dorsally but often tuberculate on the underside of the body.

Myoporum oppositifolium is an erect shrub which grows to a height of and has glabrous branches which usually have raised, wart-like tubercles. The leaves are also tuberculate, especially on the lower surface and are arranged in opposite pairs. The leaves are egg-shaped to narrow lance-shaped, long, wide and the leaf margins are serrated for their entire length. The flowers appear in groups of one to four in the axils of the leaves on a stalk long.

Their clypeus have 4 macrosetae, which are equidistant across the middle. The surface of the first segment is almost smooth and have dorsum of segments that are coriaceus and shining at the end of the body. The metazonites ventral surface is conic and tuberculate at the same time, and is located next to the keels, or rather to the posterior base which is next to it. Tubercles are continued throughout the surface and are advancing into the posterior margin.

In some specimens the entire surface is adorned with microscopic, frosty, beaded spiral threads alternating with still finer granular lines, in other shells the beaded spirals are inconspicuous over the general surface, but become progressively stronger on approaching the suture. The one bordering the suture are the strongest. The whorls contain ten undulating ribs, slightly tuberculate at the carina, extending from suture to suture. The outer lip is thickened in adult, sinus U-shaped and deep.

They are marked by the moderately strong, tuberculate, slightly retractive axial ribs, of which 16 occur upon the second and 18 upon the third and penultimate turn. In addition to the axial ribs the whorls are marked by four spiral cords between the sutures which are a little less strong than the axial ribs and render them nodulous at their junction. The spaces enclosed by the ribs and spiral cords are deep round pits. The sutures are channeled.

Rhizochaete fruit bodies have a hymenophore surface texture that ranges from smooth to tuberculate (with knots or rounded bumps). When moist, the hymenophore is membranaceous (membrane-like) to pellicular (forming a peel or thin crust). When dry, the hymenophore becomes leathery or papery, and may often be readily peeled from its substrate. The outer margin of the fruit body is fimbriate (fringed with hairs or fibres) or fibrillose (appearing as if made of fine, silky threads).

They are marked by five strong spiral keels on all the whorls between the sutures, excepting the first which has four and obsolete axial ribs on the first two. These axial ribs are best expressed near the summit of the whorls, scarcely reaching the suture, and rendering the spiral cords feebly tuberculate. On the body whorl the axial sculpture is reduced to numerous raised axial threads, like those between the cords on the base. The sutures are poorly defined.

Pristimantis mutabilis, also known as the mutable rainfrog or "punk rock" rainfrog, is a species of frog found in the Ecuadoran Andes in the Pichincha and Imbabura Provinces. Pristimantis mutabilis is the first known amphibian species that is able to change skin texture from tuberculate to almost smooth in a few minutes, an extreme example of phenotypic plasticity. The specific epithet mutabilis (changeable) refers to this ability. The physiological mechanism behind the skin texture change remains unknown.

UCMP Online Exhibits: Fossil Eggshell Arriagadoolithus shell has three layers (external, prismatic, and mammillary). The shell is approximately thick. The outer surface of its eggshell is covered with two distinct ornamentation patterns: the unique dendro-reticulate ornament, made up of randomly interconnecting ridges with nodes along the ridges or where they intersect; and the plexi- ramo-tuberculate ornament, made up of widely spaced irregularly shaped nodes and ridges. The dendro-reticulate ornamentation was found only on fragments.

The shrub typically grows to a height of has a spreading, open habit, with scabrous and tuberculate branchlets that have minute hairs. It has evergreen phyllodes with an asymmetric narrowly oblong-elliptic shape that are often shallowly incurved. The sub-glabrous to glabrous phyllodes are in length and and have a prominent midrib. It flowers between January and April producing simple inflorescences occur singly in the axils and have spherical flower-heads containing 10 to 20 pale yellow to almost white flowers.

P. tuberculata is a benthic dwelling crab species, with adults often inhabiting continental shelves. Individuals of P. tuberculata have a granulate and tuberculate carapace, with a short, backwards facing spine on the first abdominal segment. The species undergoes nine post- larval stages each separated by brief periods of molting. Beginning at the third crab stage, mature females can be differentiated from males by the large rounded sodomites which make up their abdominal plates and form a cavity to hold eggs.

Acrioceratidae is a family of heteromorph ammonites included in the Ancyloceratoidea comprising ancyloceratid-like forms that start off with a coiled juvenile section, followed by a straight or curved shaft ending in a hook. Two described genera are included, Acrioceras and Dissimilites. The Acrioceratidae form a link, or evolutionary transition, between the loosely coiled Crioceratidae and the commonly tuberculate and heavy hooked Ancyloceratidae. Although resembling Acrioceras in general form, Toxancyloceras is included in the Ancyloceratidae where it resides as a transitional form.

Collignociceras is a strongly ribbed and tuberculate, evolute ammonite from the Turonian of the western U.S. and Europe belonging to the ammonitid family Collignoniceratidae. The genus is named after the French paleontologist Maurice Collignon. The type is Collignoniceras woollgari, named by Mantell in 1822 for specimens from Sussex, England. The shell is compressed in early growth stages, with rounded or high and clavate siphonal tubercles tending to form a serrate keel, straight or slightly sinuous ribs and weak umbilical and strong ventrolateral tubercles.

All of these orders, with the Fabales, form a single nitrogen-fixing clade within the wider clade of Rosids. Some fungi produce nodular structures known as tuberculate ectomycorrhizae on the roots of their plant hosts. Suillus tomentosus, for example, produces these structures with its plant host lodgepole pine (Pinus contorta var. latifolia). These structures have in turn been shown to host nitrogen fixing bacteria which contribute a significant amount of nitrogen and allow the pines to colonize nutrient-poor sites.

These opuntioid plants grow in low opuntioid cushions, consisting of rather ovoid or slightly clavate segments, from 1 up to 25 cm long, tuberculate, not ribbed, glabrous. Spines are strong, very prickly and dangerous, covered on their margins by fine denticles, with epidermal tunica (sheath) at the apex only. Flower generally yellow, few species have pink to deep magenta flower. Fruit narrowly obconic to ellipsoid, fleshy at first but soon drying, yellow to brownish, often stinky, generally full of glochids and spiny.

Sculpture: the third, fourth and fifth whorls carry distinct spiral grooves latticed by oblique threads, which do not cross the intervening ridges. On the latter whorls this sculpture gradually fades away, leaving the body whorl smooth and polished. Around the axis on the base run four profound spiral grooves, the outer deepest, separated by smooth, prominent, narrow cords. The narrow umbilicus is bounded by a tuberculate rib, within which it is excavate, and spirally ascends the full height of the shell's interior.

Austrocactus coxii is a plant species in the genus Austrocactus from the cactus family (Cactaceae), indigenous to southern Argentina and southern Chile. It grows as short columnar stems up to 5 cm diameter, reaching 60 cm in height, with 6-10 tuberculate ribs. Central spines are hard, straight or slightly hooked, light brown to whitish and up to 4 cm long. Thin spines are interwoven and range from 6 to 10 in number; each is up to 1 cm long.

The tail is yellowish with 6 distinct, brown, semicircle bands with the spaces between broader than the banding. Regenerated tail parts are brown with cream blotches. The ventral surface of the gecko is light pink to white. The genus Parsigecko is distinguished from other genera in Gekkonidae by a combination of the following: dorsal scales that are smooth, granular, subequal in size, not tuberculate and not imbricated, and two strongly keeled scales on the sides of each annulus of the tail.

Pareuchiloglanis species have an interrupted groove behind their lips (post-labial groove), gill openings not extending onto the underside (venter), homodont dentition of pointed teeth in both jaws, tooth patches in the upper jaw joined into a band and not produced posteriorly at sides, and 13-16 branched pectoral rays. The head is depressed and the body is elongate and depressed anteriorly. The skin is smooth dorsally, but it is often tuberculate ventrally. The eyes are minute, dorsal, and under the skin (subcutaneous).

They are marked by strong, very retractive axial ribs, of which 14 occur upon the first, 16 upon the second, 18 upon the third to fifth, and 22 upon the penultimate whorl. In addition to these ribs the whorls are marked by four strong spiral cords between the sutures which render their junction with the ribs tuberculate. The spaces enclosed by the ribs and cords form oval pits, the long axis of which coincides with the spiral sculpture. The sutures are channeled.

Zones in the flesh reflect differences in growth during periods of low daytime and high nighttime humidity, and give a fairly accurate record of daily growth. The spines are crowded closely together and are typically decurrent (extending down the length of the stipe). Fruitbodies may display a variety of colors, from white to yellow, olive green, shades of orange, light brown, or dark brown in age. Spores of Hydnellum are almost spherical to oblong and tuberculate, and are brown in mass.

Placenticeratidae is an extinct family of mostly Late Cretaceous ammonites (cephalopod order Ammonitida) included in the superfamily Hoplitoidea, derived from the Engonoceratidae by an increase in suture complexity. Placeticeratids are characterized by rather involute compressed shells of moderate to large size with narrow flat or grooved venters (outer rims), at least on early whorls. Most are rather smooth or weakly ornamented except for a few later forms in which the outer whorls are strongly tuberculate. The suture has numerous, including auxiliary and adventive, elements.

Varixes are situated along the broadest section of the shell, moderately thick, repeated after a little more than half a whorl so that they are slightly and regularly offset along the spire, overrun by the spirals. The aperture is oval; outer lip faintly fluted inside; parietal and columellar edge forming a continuous callus, the parietal edge with a small but well- marked denticle, the columella is faintly tuberculate. Siphonal canal is open, moderate in length. Shell colour is from very light tan to whitish.

The fruit is in diameter, tuberculate, and may or may not have spines. These fruits contain few if any viable seeds, as the plant usually reproduces through a dispersal strategy of dropped or carried stems. These stems are often carried for some distance by sticking to the fur or skin of animals, and are known to be especially painful to remove. When a piece of this cholla sticks to an unsuspecting person, a good method to remove the cactus is with a hair comb.

The spikelets have fertile florets that are diminished at the apex while the sterile florets are barren, clumped and orbicular. Both the upper and lower glumes are keelless, membranous, long, and light green in colour. They are also have acute apexes but are different in the amount of veins and other features; Lower glume is 1–3 veined and is ovate while the upper one is only 3–5 veined and is linear. Its lemma have scabrous and tuberculate surface with an obtuse apex.

Abdominal skin impressions from Brown (1916) In the holotype of C. casuarius, the sides and tail of the body are covered in scales of several types. Polygonal tuberculate scales, covered in small bumps, vary in size over the body. Conical limpet-like scales are only preserved on a fold of skin preserved on the back of the tibia, but which was probably from the bottom of the belly, rather than the leg. Separating the polygonal scales of C. casuarius are shieldlike scales, arranged close together in rows.

As yet, no well-established clinical or geographic distinction is seen between these two genetic groups. In its asexual form, the fungus grows as a colonial microfungus strongly similar in macromorphology to B. dermatitidis. A microscopic examination shows a marked distinction: H. capsulatum produces two types of conidia, globose macroconidia, 8–15 µm, with distinctive tuberculate or finger-like cell wall ornamentation, and ovoid microconidia, 2–4 µm, which appear smooth or finely roughened. Whether either of these conidial types is the principal infectious particle is unclear.

Actea savignii has an oval carapace which is slightly convex on the dorsal surface with a flat median region and a width which is about 1.3 times its length; the dorsal regions of the carapace have a covering of large, smooth, rounded, petal-shaped, dense tubercles. The anterolateral margin is slightly curved and is divided into four vaguely defined, tuberculate, rounded lobes while the anteriormost is barely marked. The posterolateral margin is shorter and slightly concave. The posterior margin is straight and bears a prominent row of tubercles.

A wild form of the plant as a distinct species is unknown, with Datura metel, as currently described, forming essentially a group of ancient cultivars likely attributable to pre- Columbian horticultural practices. Symon and Haegi noted in 1991 the occurrence on the island of Cuba of an apparently wild plant given the name Datura velutinosa V.R. FuentesRevista Jard. Bot. Nac. Univ. Habana 1: 53 1980 publ. 1981. (no longer an accepted species and now listed as a form of D. innoxia), the capsules of which are tuberculate like those of D. metel.

It has been observed to attack other pruni larvae which had fastened themselves before moulting (Frohawk). Pupa anteriorly somewhat angular, black-brown, with darker markings and a pale saddle-patch, the abdomen being tuberculate and strongly raised, the whole resembling a small bud or bird-droppings. The butterflies appear in June, usually flying singty, being so abundant however in certain years that one can easily obtain several dozen within an hour. At such occasions they fly about the twigs of the food-trees and the undergrowth beneath them; they are very partial to flowering privet.

Hydnellum is classified in the family Bankeraceae, which was circumscribed by Marinus Anton Donk in 1961. Donk's original family concept included the genera Bankera and Phellodon, whose species produce hyaline (translucent) and echinulate spores (covered with small spines). Donk also noted that Bankeraceae species lacked clamp connections. When clamp connections were discovered in Phellodon fibulatus and tuberculate spore ornamentation (the presence of small nodules on the spores) was found in P. niger, Kenneth Harrison thought the family Bankeraceae was superfluous, and placed Phellodon and Bankera in the family Hydnaceae.

This slow-growing species is closely related to the similar, but much larger, Gasteria nitida species of the South African grasslands, and their bright reddish-pink flowers are very similar. (In some classification schemes, it is even classed as a variety within this species, and in cultivation G. armstrongii can resemble juvenile plants of G. nitida.) For those who treat it as a separate species, Gasteria armstrongii can be distinguished by its very dark, retuse, distichous, roughly tuberculate leaves. Its inflorescences are also solitary. (G. nitida is much larger, with smooth leaves that grow in a rosette, not distichous.

They are marked by very strong, rounded, axial ribs, of which 14 occur upon the first, 16 upon the second, 18 upon the third, 20 upon the fourth, 22 upon the fifth, and 24 upon the penultimate turn. In addition to the axial ribs the whorls are marked by spiral cords, less strong than the ribs, the junctions of which with the ribs render them tuberculate. Of these cords, four occur upon all the whorls but the penultimate and last, which have five between the sutures. The spaces enclosed between the ribs and cords are deep square pits.

It is a large Chaceon, its size varying from to , with small anterolateral teeth on the carapace and laterally-compressed dactyli on the walking legs. Its median pair of frontal teeth is narrower than the laterals, separated by a U-shaped emargination. The carapace has a distinct granulation medial to the fifth tooth and on protogastric, cardiac, and branchial regions; its hepatic region is smooth; protogastric region inflated in large specimens, especially in females. Its cheliped is lightly tuberculate dorsally; upper margin of merus with a sharp subdistal spine; the carpus lacking an outer spine in adults; propodus unarmed distally.

Many of the members of this family are small, cryptically colored fishes with tuberculate skin. Erethistids are distinguished from sisorids by having a pectoral girdle with a long coracoid process that extends well beyond the base of the pectoral fin; this structure can be felt through the skin in all genera and is visible externally in all genera except Pseudolaguvia. Erethistids differ from amblicipitids in that they lack a cuplike fold of skin in front of the pectoral fin (vs. possessing the cuplike fold), and have a dorsal fin with a strong spine and no thick covering of skin (vs.

They are marked by strong protractive axial ribs, of which 16 occur upon the second, 18 upon the third, and 20 upon the remaining turns. In addition to the axial ribs the whorls are marked by four slender spiral cords between the sutures, which render the ribs tuberculate at their junction. The spaces enclosed by the ribs and spiral cords are deep, quadrangular pits, the long axis of which coincides with the spiral cords. The periphery of the body whorl is marked by a strong sulcus which is crossed by the continuation of the axial ribs.

The front margin is strongly curved, and is equivalent to about 0.35 times the width of the carapace, it has two lobes along the sinuous frontal margin; the two lobes being divided by a wide V-shaped cleft. Almost the entire under surface is densely tuberculate; with the tubercles flattened and densely packed but varying in size, partly simple and partly petal-like in shape. The claws are subequal, heavy and also covered in dense tubercles. The fingers are distinctly shorter than the palm; with the proximal portion of the movable finger densely covered with flattened tubercles, and bearing two to three larger tubercles which form teeth.

54 (24): 407-462. Small individual from Singapore Scales in 25-27 longitudinal rows at midbody; 11-13 upper labials, the first partially or completely united with the nasal; supraocular very narrow, sometimes broken into small scales, 12-15 scales between them; head scales small, subequal, tuberculate or granular; temporal scales keeled. Body color highly variable: above olive, grayish, to dark purplish brown; below whitish, greenish or brown, uniform or spotted with brown; a light line on scale row one bordering ventrals present or absent; head olive, heavily suffused with brown. Ventrals: males 160-179, females 168-183; subcaudals: males 74-76, females 56-63, paired; hemipenes without spines.

The plants are usually small, globose to elongated, the stems from 1 cm to 20 cm in diameter and from 1 cm to 40 cm tall, clearly tuberculate, solitary to clumping forming mounds of up to 100 heads and with radial symmetry. Tubercles can be conical, cylindrical, pyramidal or round. The roots are fibrous, fleshy or tuberous. The flowers are funnel-shaped and range from 7 mm to 40 mm and more in length and in diameter, from white and greenish to yellow, pink and red in colour, often with a darker mid-stripe; the reddish hues are due to betalain pigments as usual for Caryophyllales.

Liocranchia reinhardti In the cranchiids Leachia cyclura and Liocranchia reinhardti, the dermal tubercles are not distributed throughout the mantle but arranged in discrete cartilaginous bands. A role in buoyancy control is therefore unlikely. One possibility is that these rigid bands play a pseudoskeletal role, maintaining the shape of parts of the mantle during swimming contractions or providing attachment points for mantle muscles or visceral tissue (such as the septum covering the coelom). The very dense tuberculate ridges found on the arms and dorsal mantle of Histioteuthis meleagroteuthis may similarly provide insertion points for muscles, and are probably most important in juvenile animals, which lack well-developed musculature.

The first 3 whorls are smooth, the next 4 or 5 whorls having a smooth carina projecting above the suture, the first 2½ of them tuberculate, after which the carina is smooth. The following whorls are less steeply sloping, very slightly concave, marked with fine growth lines and a few weak spiral striae, slightly prominent at the sutures. The body whorl is acutely carinate, the slope below the angle almost straight, but just perceptibly convex in the upper, concave in the lower half, which is sculptured with about 16 rather strong spiral cords. The outer lip arches strongly forward and is deeply retracted at the upper end.

The eastern white pine (Pinus strobus) is the predominant North American mycorrhizal associate of Suillus spraguei. In nature, Suillus spraguei forms ectomycorrhizal relationships with five-needled pine species. This is a mutually beneficial relationship where the hyphae of the fungus grow around the roots of the trees, enabling the fungus to receive moisture, protection and nutritive byproducts of the tree, and affording the tree greater access to soil nutrients. S. spraguei produces tuberculate ectomycorrhizae (covered with wart-like projections) that are described as aggregates of ectomycorrhizal roots encased in a fungal rind, and rhizomorphs that are tubular fungal cords with a hard outer sheath.

The six whorls of the teleoconch are well rounded, and moderately contracted at the suture, with a sloping shoulder which extends over the posterior third between the sutures. Th whorls are marked by slender, well-rounded, slightly retractive axial ribs, of which 18 occur upon the first, 20 upon the second and third, 22 upon the fourth, and 32 upon the penultimate turn. The intercostal spaces are about one and one-half times as wide as the ribs upon all but the last whorl. They are marked by five spiral series of broad pits, which are wide as the five cord-like interspaces which they bound and which render the ribs somewhat tuberculate at their junction.

Species in the genus Echinodontium have a hydnaceous (with spinelike protuberances) hymenial surface, dimitic hyphal system, smooth basidiospores, and in three of four species, a symbiotic association with horntails — Sirex and Urocerus species. The insects eat the fungus and help disperse the species by inoculating the wood of the host tree with either hyphal fragments or spores when they lay their eggs. The genus Laurilia has species characterized by an even to tuberculate hymenial surface, dimitic hyphal system, and echinulate basidiospores. In his monograph on the Echinodontiaceae, Gross (1964) suggested that Echinodontium and Laurilia were congeneric (sharing the same taxonomic genus), sharing features such as clamp connections, thick-walled encrusted cystidia and a brown context.

Otoidtidae: stephanoceratoid ammonitina from the early Middle Jurassic that begin as cadicones but become more planualte with age; derived from the Hammitoceratidae (Hildoceratoidea), probably through Erycites by way of Abbasites. Shells begin barrel shaped with depressed whorls, broad outer rims, and deep, crater-like umbilici—cadiconic—but become compressed, with the out rims becoming bluntly rounded—planulate. Ribbing is common; may be heavy and tuberculate on the umbilical shoulders and may divide along the flanks before crossing the outer rim -the venter- uninterrupted. The Otoitidae is the ancestral family of the Stephanoceratoidea and is known only from a relatively short interval of time within the Bajocian stage at the beginning the Middle Jurassic and begins with Docidoceras.

This taxonomic rearrangement was rejected by Rudolph Arnold Maas Geesteranus in 1974, who showed that the tuberculate spores of P. niger were the result of an immature specimen. Richard Baird and Saeed Khan investigated spore ornamentation in North American Phellodon species using scanning electron microscopy, and rejected the placement of Phellodon in the Bankeraceae, preferring to leave it and Bankera in the Hydnaceae. Modern molecular phylogenetic analysis places Phellodon in the thelephoroid clade (roughly equivalent to the order Thelephorales) along with the related genera Bankera, Hydnellum, and Sarcodon. Although the status of the Bankeraceae has not been fully clarified with molecular genetic techniques, Phellodon is classified in this family by authorities on fungal taxonomy.

There may be three sharp spirals on each of the four spire-whorls in a shell 8 mm. long, or two on the first and second spire- whorls, an intercalated third thread on the third whorl, and three on the fourth whorl. The shell may be shorter and more solid, with two very strong spirals on all the spire-whorls, and a weak intercalated thread on the fourth, with about twenty obsolete axial lirae on the second and third whorls, much less marked on the fourth. It may be short and wide, with only two spirals in the spire-whorls, but in the first and second, or first, second, and third whorls oblique axial lirae almost as valid as the spirals may cross and tuberculate these, and fade out in the later whorls.
