Auricularia americana is a species of fungus in the family Auriculariaceae found in North America and East Asia. Its basidiocarps (fruitbodies) are gelatinous, ear-like, and grow on dead conifer wood.
The species was originally described in 1987 from Quebec on Abies balsamea , but was not validly published until 2003. Molecular research, based on cladistic analysis of DNA sequences, has shown that Auricularia americana is a distinct species. [1] [2]
The species was formerly confused with Auricularia auricula-judae , which grows on broadleaf wood and is confined to Europe.[ citation needed ]
Auricularia americana forms thin, brown, rubbery-gelatinous fruit bodies that are ear-shaped and 2.5–10 centimetres (1–4 inches) across and about 3 millimetres (1⁄8 in) thick. [3] The fruitbodies occur singly or in clusters. The upper surface is finely pilose. The spore-bearing underside is smooth. [2] The spore print is white. [3]
The microscopic characters are typical of the genus Auricularia . The basidia are tubular, laterally septate, 55–70 × 4–5 μm. The spores are allantoid (sausage-shaped), 14–16.5 × 4.5–5.5 μm. [2]
In North America, Auricularia angiospermarum is almost identical but grows on the wood of broadleaf trees. No other North American Auricularia species grows on conifer wood. In China and Tibet, however, a second species, A. tibetica , also occurs on conifers. It can be distinguished microscopically by its longer basidia and larger basidiospores. [1] [2]
Additionally, A. nigricans , Exidia crenata , and Phylloscypha phyllogena are similar. [3]
Auricularia americana is a wood-rotting species, typically found on dead attached or fallen wood of conifers. It is widely distributed in North America (primarily in the Northeast, between April and September) [3] and is also known from China and the Russian Far East. [2]
Jelly fungi are a paraphyletic group of several heterobasidiomycete fungal orders from different classes of the subphylum Agaricomycotina: Tremellales, Dacrymycetales, Auriculariales and Sebacinales. These fungi are so named because their foliose, irregularly branched fruiting body is, or appears to be, the consistency of jelly. Actually, many are somewhat rubbery and gelatinous. When dried, jelly fungi become hard and shriveled; when exposed to water, they return to their original form.
Auricularia cornea, also known as cloud ear, is a species of fungus in the order Auriculariales. It is commercially cultivated for food in China. Auricularia cornea is a popular ingredient in many Chinese dishes and is also used in traditional Chinese medicine.
Pseudohydnum gelatinosum, commonly known as the toothed jelly fungus, cat's tongue, or jelly tooth, is an Eurasian species of fungus in the order Auriculariales. Its common names refer to its gelatinous consistency and hydnoid (toothed) undersurface.
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.
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 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.
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. The fruit bodies 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.
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 nigricans 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 found in southern and eastern Asia, North America, South America and the Caribbean. Asian examples were formerly considered as a separate species described as Auricularia polytricha.
Phaeotremella frondosa is a species of fungus in the family Phaeotremellaceae producing brownish, frondose, gelatinous basidiocarps. It is widespread in north temperate regions, and is parasitic on other species of fungi that grow on dead attached and recently fallen branches of broadleaf trees.
Phaeotremella foliacea is a species of fungus in the family Phaeotremellaceae. It produces brownish, frondose, gelatinous basidiocarps and is parasitic on the mycelium of Stereum sanguinolentum, a fungus that grows on dead attached and recently fallen branches of conifers. It is widespread in north temperate regions. In the UK it has the recommended English name leafy brain and has also been called jelly leaf and brown witch's butter. Prior to 2017, the name Tremella foliacea was also applied to similar-looking species on broadleaf trees, now distinguished as Phaeotremella frondosa and Phaeotremella fimbriata.
Naematelia aurantia is a species of fungus producing yellow, frondose, gelatinous basidiocarps. It is widespread in north temperate regions and is parasitic on another species of fungus that grows on dead attached and recently fallen branches of broadleaf trees. It is commonly called golden ear in North America.
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 heimuer, also known as heimuer or black wood ear, is a species of fungus in the order Auriculariales. It is commercially cultivated for food in China at a value exceeding $4 billion (USD) per year. The species was previously referred to as the European Auricularia auricula-judae, but the latter is not known to occur in east Asia. Auricularia heimuer is a popular ingredient in many Chinese dishes, such as hot and sour soup, and it is also used in traditional Chinese medicine.
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.

It typically grows on dead attached twigs and branches of birch and has been recorded from Europe, North America, and Japan.
Exidia candida is a species of fungus in the family Auriculariaceae. Basidiocarps are gelatinous, whitish, and cushioned-shaped at first, becoming effused and corrugated.
