Pseudohydnum gelatinosum is a species of fungus in the order Auriculariales. It has the recommended English name of jelly tooth, with reference 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 but distinct species elsewhere. At least three species occur in North America, but these are currently unnamed. P. gelatinosum grows on dead conifer wood.
The Auriculariales are an order of fungi in the class Agaricomycetes. Species within the order were formerly referred to the "heterobasidiomycetes" or "jelly fungi", since many have gelatinous basidiocarps that produce spores on septate basidia. Around 200 species are known worldwide, placed in six or more families, though the status of these families is currently uncertain. All species in the Auriculariales 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.
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.
The Hyaloriaceae are a family of fungi in the order Auriculariales. Species within the family have gelatinous basidiocarps that produce spores on septate basidia and, as such, were formerly referred to the "heterobasidiomycetes" or "jelly fungi". All appear to be saprotrophic, growing on dead wood or plant remains. Less than 30 species are currently included within the Hyaloriaceae, but the family has not been extensively researched.
Auricularia is a genus of fungi in the family Auriculariaceae. Basidiocarps are typically gelatinous and ear-shaped, with a slightly downy to conspicuously hirsute upper surface and an under surface that is smooth, wrinkled or veined. All species grow on wood. Several Auricularia species are edible and commercially cultivated on a large scale in China and East Asia.
Exidia is a genus of fungi in the family Auriculariaceae. The species are saprotrophic, occurring in attached or recently fallen dead wood, and produce gelatinous basidiocarps. The fruit bodies are diverse, pustular, lobed, button-shaped or cup-shaped. Several species, including the type species Exidia glandulosa, have sterile pegs or pimples on their spore-bearing surface. The genus has a cosmopolitan distribution and around 20 species are currently recognized worldwide. Initial molecular research indicates the genus is artificial.
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus Hydnum, but it is now known that not all hydnoid species are closely related.
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 contains some twelve 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.
Ceratobasidium is a genus of fungi in the order Cantharellales. Basidiocarps are effused and the genus is sometimes grouped among the corticioid fungi, though species also retain features of the heterobasidiomycetes. Anamorphic forms were formerly referred to the genus Ceratorhiza, but this is now considered a synonym of Rhizoctonia. Ceratobasidium species, excluding the type, are also now considered synonymous with Rhizoctonia and some species have been transferred to the latter genus. Species are saprotrophic, but several are also facultative plant pathogens, causing a number of commercially important crop diseases. Some are also endomycorrhizal associates of orchids.
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.
Aporpium is a genus of fungi in the order Auriculariales. Basidiocarps are formed on dead wood and have a poroid hymenium. Species were often formerly referred to the genera Elmerina or Protomerulius, but molecular research, based on cladistic analysis of DNA sequences, has shown that Aporpium is a distinct, mainly north temperate genus.
Elmerina is a genus of fungi in the order Auriculariales. Basidiocarps are formed on dead wood and are either bracket-like with a poroid hymenium or densely clavarioid. Species are known from East Asia and Australia.
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.
Protohydnum is a genus of fungi in the order Auriculariales. Protohydnum cartilagineum, the type and only species, occurs in Central and South America and produces effused, cartilaginous basidiocarps on wood, yellow-ochre and wholly covered in small spines. Molecular research, based on cladistic analysis of DNA sequences, has shown that the genus is distinct, but that other species previously referred to Protohydnum belong in the genera Hyalodon or Elmerina.
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.
Heteroacanthella is a genus of fungi in the order Auriculariales. Basidiocarps are corticioid with smooth surfaces and occur on dead, attached wood or on lichens. They are microscopically distinctive in having acanthoid (spiny) basidia with just one or two large sterigmata producing large, globose to ellipsoid basidiospores. The genus occurs worldwide, though individual species may be localized. Three species have been described to date.
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.
