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.
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.
Exidia glandulosa, commonly known as black witches' butter, black jelly roll, or warty jelly fungus, is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species in Europe, typically growing on dead attached branches of oak. The fruit bodies are up to 3 cm (1.2 in) wide, shiny, black and blister-like, and grow singly or in clusters. Its occurrence elsewhere is uncertain because of confusion with the related species, Exidia nigricans.
Exidia nigricans is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species throughout the northern hemisphere, typically growing on dead attached branches of broadleaf trees. It has been much confused with Exidia glandulosa.
Exidia recisa is a species of fungus in the family Auriculariaceae. In the UK, it has the recommended English name of amber jelly. Basidiocarps are gelatinous, orange-brown, and turbinate (top-shaped). It typically grows on dead attached twigs and branches of willow and is found in Europe and possibly elsewhere, though it has long been confused with the North American Exidia crenata.
Exidia thuretiana is a jelly fungus in the family Auriculariaceae. The fruit bodies are white and gelatinous with brain-like folds. It is a common, wood-rotting species in Europe, typically growing on dead attached or fallen branches of broadleaf trees, especially beech.
Myxarium nucleatum is a species of fungus in the family Hyaloriaceae. In the UK, it has been given the recommended English name of crystal brain. Basidiocarps are watery white, pustular or lobed, and gelatinous with small, white, mineral inclusions visible to the naked eye. It is a common, wood-rotting species in Europe, typically growing on dead attached or fallen branches of broadleaf trees. It is currently not clear whether collections from North America and elsewhere represent the same species.
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.
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.
Auricularia auricula-judae, commonly known as wood ear, jelly ear, or more historically, Jew's ear, is a species of fungus in the order Auriculariales. Basidiocarps are brown, gelatinous, and have a noticeably ear-like shape. They grow on wood, especially elder. The specific epithet is derived from the belief that Judas Iscariot hanged himself from an elder tree.
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.
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.
Exidia repanda is a species of fungus in the family Auriculariaceae. In the UK, it has the recommended English name of birch jelly. Basidiocarps are gelatinous, orange-brown, and button-shaped. It typically grows on dead attached twigs and branches of birch and has been recorded from Europe, North America, and Japan.
Exidia purpureocinerea is a species of fungus in the family Auriculariaceae. Basidiocarps are gelatinous, densely covered in small spines, purple-grey, and cushioned-shaped at first, becoming effused. The species occurs in southern Africa on dead wood.
Exidia umbrinella is a species of fungus in the family Auriculariaceae. Basidiocarps are gelatinous, orange-brown, and turbinate (top-shaped). It grows on dead attached twigs and branches of conifers in Europe.
