Heterochaete is a genus of fungi in the order Auriculariales. Species produce effused, gelatinous, waxy, or leathery basidiocarps (fruit bodies) 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.

Heterochaete was monographed by Bodman in 1952 who accepted some 29 species worldwide, most of them from the tropics and subtropics. [1] On the basis of morphological differences, Bodman considered the genus to be heterogeneous [1] and this has been confirmed by molecular research, based on cladistic analysis of DNA sequences. As a result, several species previously placed in Heterochaete have now been referred to the genera Crystallodon , Eichleriella , Heteroradulum , Hirneolina , Metulochaete , and Tremellochaete . [2] [3] [4]

DNA research has also indicated that the type species, H. andina, is congeneric with Exidiopsis making Heterochaete an earlier name for Exidiopsis , though no name changes have yet been made on this basis. [2] [3] Most of the 30 or so residual species in Heterochaete have yet to be re-assessed.

<i>Pseudohydnum</i> Genus of fungi

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 contains some twelve species.

<i>Heteroradulum</i> Genus of fungi


Heteroradulum is a genus of fungi in the order Auriculariales. Species produce effused, leathery basidiocarps on wood, often pinkish red and partly or wholly covered in small sterile spines. The genus was originally published in 1917 by American mycologist Curtis Gates Lloyd under the facetious pseudonym "McGinty", rendering the name invalid. It was validated a century later to accommodate a group of species formerly placed in the genera Eichleriella or Heterochaete, but not closely related to either.

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.

<i>Basidiodendron</i> Genus of fungi

Basidiodendron is a genus of fungi in the order Auriculariales. Basidiocarps are corticioid, thin, effused and are typically found on fallen wood. The genus is widespread in both temperate and tropical regions and contains over 30 species.

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.

<i>Auricularia americana</i> Species of fungus

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.

<i>Auricularia angiospermarum</i> Species of fungus

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.

<i>Myxarium</i> Genus of fungi

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.

Proterochaete is a genus of fungi in the family Auriculariaceae. The type and only species, Proterochaete adusta, produces thin, effused, corticioid basidiocarps with a smooth or spiny surface on wood. The species was originally described from North America and is also known from northern Europe and Asia.

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.

<i>Protodaedalea</i> Genus of fungi

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.
