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.

Taxonomy

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]

Description

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]

Microscopic characters

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]

Habitat, ecology and distribution

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]

Uses

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]

<span class="mw-page-title-main">Jelly fungus</span> Group of fungi

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.

The specific epithet is derived from the belief that Judas Iscariot hanged himself from an elder tree.

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

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.

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.

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

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.
