Pseudohydnum gelatinosum, commonly known as the toothed jelly fungus, cat's tongue, or jelly tooth, is a species of fungus in the order Auriculariales. It's common names refer to its gelatinous consistency and hydnoid (toothed) undersurface. The species was thought to be cosmopolitan, but recent DNA evidence suggests that it is confined to Europe and northern Asia, with superficially-similar taxa elsewhere. A subspecies, Pseudohydnum gelatinosum ssp. pusillum, is found in North America. P. gelatinosum grows on dead conifer wood.
The Auriculariaceae are a family of fungi in the order Auriculariales. Species within the family were formerly referred to the "heterobasidiomycetes" or "jelly fungi", since many have gelatinous basidiocarps that produce spores on septate basidia. Around 100 species are known worldwide. All are believed to be saprotrophic, most growing on dead wood. Fruit bodies of several Auricularia species are cultivated for food on a commercial scale, especially in China.
Pseudohydnum is a genus of fungi in the order Auriculariales. Basidiocarps are typically bracket-like and gelatinous, with or without a stipe, with a hydnoid (toothed) undersurface. The genus is widely distributed in both the northern and southern hemisphere, with thirteen species currently described and others awaiting description.
Eichleriella is a genus of fungi in the order Auriculariales. Species produce effused or cupulate, waxy to leathery basidiocarps on wood, with a smooth to spiny surface. The genus currently contains more than 15 species.
Heterochaete is a genus of fungi in the order Auriculariales. Species produce effused, gelatinous, waxy, or leathery basidiocarps on wood, partly or wholly covered in small sterile spines or pegs. The presence of these sterile spines distinguishes the genus from Exidiopsis, species of which are microscopically similar but have smooth basidiocarps.
The Ceratobasidiaceae are a family of fungi in the order Cantharellales. All species within the family have basidiocarps that are thin and effused. They have sometimes been included within the corticioid fungi or alternatively within the "heterobasidiomycetes". Species are saprotrophic, but some are also facultative plant pathogens or are associated with orchid mycorrhiza. Genera of economic importance include Ceratobasidium and Rhizoctonia, both of which contain plant pathogenic species causing diseases of commercial crops and turf grass.
Protomerulius is a genus of fungi in the order Auriculariales. Basidiocarps are formed on dead wood and have an effused, smooth, spiny, or poroid hymenium. The genus is cosmopolitan.
Auricularia americana is a species of fungus in the family Auriculariaceae. Basidiocarps (fruitbodies} are gelatinous, ear-like, and grow on dead conifer wood. The species was formerly confused with Auricularia auricula-judae, which grows on broadleaf wood and is confined to Europe.
Auricularia angiospermarum is a species of fungus in the family Auriculariaceae. Basidiocarps (fruitbodies) are gelatinous, ear-like, and grow on dead wood of broadleaf trees. It is a North American species and was formerly confused with Auricularia auricula-judae which is confined to Europe.
Auricularia mesenterica, commonly known as the tripe fungus, is a species of fungus in the family Auriculariaceae. Basidiocarps are gelatinous and typically formed in coalescing tiers on stumps and logs. They are partly pileate, with hirsute, zoned caps, and partly resupinate, with smooth to wrinkled undersurfaces that spread over the wood. Auricularia mesenterica is a saprotroph on dead deciduous trees and shrubs. The species is restricted to Europe and Central Asia.
Myxarium is a genus of fungi in the family Hyaloriaceae. Basidiocarps are gelatinous and effused or pustular. The genus is cosmopolitan. All species grow on dead wood or dead herbaceous stems.
Adustochaete is a genus of fungi in the family Auriculariaceae. Species produce effused basidiocarps on wood, typically covered in small sterile spines or pegs. The genus was created as a result of molecular research, based on cladistic analysis of DNA sequences, to accommodate two species from Brazil and Mexico that are not closely related to the older and superficially similar genus Heterochaete. Two additional species, from Brazil and China, have since been described.
Tremellochaete is a genus of fungi in the family Auriculariaceae. Species produce pustular or lobed, effused, gelatinous basidiocarps on wood, typically covered in small sterile spines or pegs.
Amphistereum is a genus of fungi in the family Auriculariaceae. Species produce cupulate to effused, leathery basidiocarps on wood. Microscopically, fruit bodies have a dimitic hyphal system. The genus is currently only known from North and South America.
Sclerotrema is a genus of fungi in the family Auriculariaceae. The type and only species, Sclerotrema griseobrunnea, produces effused, corticioid basidiocarps on wood with a smooth surface. The species was originally described from Russia and is also known from Canada.
Protodaedalea is a genus of fungi in the family Auriculariaceae. Species produce bracket-like basidiocarps on wood with a lamellate (gilled) undersurface. The genus currently comprises two species, both known from Asia.
Hyalodon is a genus of fungi in the order Auriculariales. Species occur on dead wood in Europe and Asia, producing effused, gelatininous basidiocarps covered in small spines. Molecular research, based on cladistic analysis of DNA sequences, has shown that the genus is distinct.
Mycostilla is a genus of fungi in the order Auriculariales. The type and only species, Mycostilla vermiformis, forms effused, gelatinous, crystalline or net-like basidiocarps on fallen conifer wood in Europe. The species was formerly placed in Stypella, but the latter genus is of uncertain disposition and appears unrelated to the Auriculariales. Molecular research, based on cladistic analysis of DNA sequences, distinguishes Mycostilla from the morphologically similar genus Stypellopsis.
Stypellopsis is a genus of fungi in the order Auriculariales. Basidiocarps are effused, gelatinous, crystalline or net-like and occur on fallen conifer wood. Species were formerly placed in Stypella or Protomerulius, but molecular research, based on cladistic analysis of DNA sequences, distinguishes Stypellopsis from these genera and from the morphologically similar genus Mycostilla. The type species occurs in northern Europe, Stypellopsis farlowii in North America.
Heterocorticium is a genus of fungi in the family Auriculariaceae. Basidiocarps are corticioid (effused), with a smooth surface, and occur on bamboo or wood. Two species have been described, both from China.
