Auricularia is a genus of fungi in the family Auriculariaceae. Basidiocarps (fruit bodies) 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.
The genus was first introduced in 1780 by French mycologist Pierre Bulliard for a range of different fungi producing fruit bodies with an ear-like shape. In 1822 Christian Hendrik Persoon restricted the genus to two gelatinous species, Auricularia mesenterica (which became the type species) and A. sambuci (a synonym of Auricularia auricula-judae ). [2] In 1848 Swedish mycologist Elias Magnus Fries accepted A. mesenterica within the genus but, on the basis of differences in fruitbody appearance, introduced a new genus, Hirneola, for most other species. [3] This division into two genera was maintained by some authors until at least the 1960s, [4] though American mycologist Bernard Lowy's monograph of the genus had accepted Hirneola as a synonym of Auricularia in 1952 . [5]
Molecular research, based on cladistic analysis of DNA sequences, has shown that Auricularia (including Hirneola) forms a natural, monophyletic grouping. It has also shown that many species are more restricted in distribution than previously thought, resulting in the description of additional new taxa. [6] [7] [8]
All species of Auricularia form thin, brownish, rubbery-gelatinous fruit bodies that are shelf-like or ear-shaped and up to 120 mm (4.7 in) across and 5 mm (0.20 in) thick. The fruitbodies occur singly or in clusters. The upper surface is finely pilose to densely hirsute. The spore-bearing underside is smooth, wrinkled, veined, or reticulate (net-like). [8] Unpigmented white forms are occasionally encountered. [9] [10]
The spore-producing basidia are tubular, laterally septate, and (in some species) up to 100 μm long. The spores are allantoid (sausage-shaped), and (in some species) up to 22 μm long. Hairs on the upper surface are thick-walled, rounded or acute at the tip, and (in some species) up to 1 cm (0.39 in) long. When sectioned, some species show a central, medulla layer of parallel hyphae, others lack such a layer. [8]
All species grow on wood and are saprotrophic wood-rotters, producing a white rot. [11] Most occur on dead wood, but they can also be weakly parasitic on living wood. The majority of species grow on broadleaf trees and shrubs, but a few grow on conifers. Fruit bodies occur singly, in clusters, or in tiers. [5] [8]
The genus has a global distribution, with some species confined to the tropics, others to north temperate regions, and others to south temperate regions. [5] [8]
At least three species are commercially cultivated for food on a large scale in China and East Asia. They include Auricularia heimuer (black wood ear), formerly misdetermined as Auricularia auricula-judae ; [12] [7] Auricularia cornea (wood ear or cloud ear), also called A. polytricha; and Auricularia villosula . [8]
Other species are eaten locally around the world. A study on the use of fungi by the Bini people of southern Nigeria found that the local inhabitants collected and ate a species similar to A. auricula-judae, but that it was not one of the fungi they used medicinally. [13] Collection of Auricularia species has also been documented in Nepal. However, the Nepalese do not consider them all that good for eating; of the three grades given to edible fungi, they were given the worst. [14] Additional places where Auricularia species have been recorded as locally gathered and consumed include Benin, Chile, Fiji, Ghana, Guatemala, India, Indonesia, Madagascar, Mexico, Mozambique, and Poland. [15]
Several species, including the Asian cultivated species and the European A. auricula-judae (jelly ear or jew's ear), have been used in traditional medicine. [16] They have also been investigated for potential pharmaceutical use. [12]

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.
Tremella fuciformis is a species of fungus; it produces white, frond-like, gelatinous basidiocarps. It is widespread, especially in the tropics, where it can be found on the dead branches of broadleaf trees. This fungus is commercially cultivated and is one of the most popular fungi in the cuisine and medicine of China. T. fuciformis is commonly known as snow fungus, snow ear, silver ear fungus, white jelly mushroom, and white cloud ears.
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.
Wood-ear or tree ear, also translated wood jellyfish or tree jellyfish, can refer to a few similar-looking edible fungi used primarily in Chinese cuisine; these are commonly sold in Asian markets shredded and dried.
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.
Tremella is a genus of fungi in the family Tremellaceae. All Tremella species are parasites of other fungi and most produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the "jelly fungi". Over 100 species of Tremella are currently recognized worldwide. One species, Tremella fuciformis, is commercially cultivated for food.
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.
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 is a genus of fungi in the family Phaeotremellaceae. All Phaeotremella species are parasites of other fungi and produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the "jelly fungi". Fifteen or so species of Phaeotremella are currently recognized worldwide. Tremella sanguinea, shown to be a Phaeotremella species by DNA sequencing, is cultivated in China as an ingredient in traditional Chinese medicine.
Naematelia is a genus of fungi in the family Naemateliaceae. All Naematelia species are parasites of other fungi and produce anamorphic yeast states. When produced, Basidiocarps ,, are gelatinous and are colloquially classed among the "jelly fungi."Four species of Naematelia are currently recognized worldwide. One species, Naematelia aurantialba, is commercially cultivated for food.
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 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.
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.
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.
