Hypoxylon is a genus of ascomycetes commonly found on dead wood, and usually one of the earliest species to colonise dead wood. A common European species is Hypoxylon fragiforme which is particular common on dead trunks of beech.
Based on morphological studies and gene sequence analyses, 27 species formerly assigned to Hypoxylon sect. Annulata were reassigned to a new genus called Annulohypoxylon in 2005. [2]
Research in Iran has shown the potential of some species of Hypoxylon in producing chemicals that are antagonistic against the disease Ash dieback. [3]
Some species in the genus Hypoxylon may be used in the cultivation of Tremella fuciformis , one of the foremost medicinal and culinary fungi of China and Taiwan. [4]
Tremella fuciformis is a parasitic yeast that does not form an edible fruitbody without parasitizing another fungus. [4] Its preferred host, formerly known as Hypoxylon archeri, [4] was moved to the closely related genus Annulohypoxylon and is now known as Annulohypoxylon archeri . [2] Cultivators usually pair cultures of Tremella fuciformis with this species, but mushroom cultivation books written before the new genus was created suggest other Hypoxylon species may be used. [4]
Morchella, the true morels, is a genus of edible sac fungi closely related to anatomically simpler cup fungi in the order Pezizales. These distinctive fungi have a honeycomb appearance due to the network of ridges with pits composing their caps. Morels are prized by gourmet cooks, particularly in Catalan and French cuisine. Due to difficulties in cultivation, commercial harvesting of wild morels has become a multimillion-dollar industry in the temperate Northern Hemisphere, in particular North America, Turkey, China, the Himalayas, India, and Pakistan where these highly prized fungi are found in abundance.
Psilocybe is a genus of gilled mushrooms, growing worldwide, in the family Hymenogastraceae. Most or nearly all species contain the psychedelic compounds psilocybin and psilocin.
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.
The Hymenochaetales are an order of fungi in the class Agaricomycetes. The order in its current sense is based on molecular research and not on any unifying morphological characteristics. According to one 2008 estimate, the Hymenochaetales contain around 600 species worldwide, mostly corticioid fungi and poroid fungi, but also including several clavarioid fungi and agarics. Species of economic importance include wood decay fungi in the genera Phellinus and Inonotus sensu lato, some of which may cause losses in forestry. Therapeutic properties are claimed for Inonotus obliquus ("chaga") and Phellinus linteus, both of which are now commercially marketed.
Tremella mesenterica is a common jelly fungus in the family Tremellaceae of the Agaricomycotina. It is most frequently found on dead but attached and on recently fallen branches, especially of angiosperms, as a parasite of wood decay fungi in the genus Peniophora. The gelatinous, orange-yellow fruit body of the fungus, which can grow up to 7.5 cm (3.0 in) diameter, has a convoluted or lobed surface that is greasy or slimy when damp. It grows in crevices in bark, appearing during rainy weather. Within a few days after rain it dries into a thin film or shriveled mass capable of reviving after subsequent rain. This fungus occurs widely in deciduous and mixed forests and is widely distributed in temperate and tropical regions that include Africa, Asia, Australia, Europe, North and South America. Although considered bland and flavorless, the fungus is edible. Tremella mesenterica produces carbohydrates that are attracting research interest because of their various biological activities.
Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms, P. ostreatus. Species of Pleurotus may be called oyster, abalone, or tree mushrooms, and are some of the most commonly cultivated edible mushrooms in the world. Pleurotus fungi have also been used in mycoremediation of pollutants, such as petroleum and polycyclic aromatic hydrocarbons.
Agaricomycotina is one of three subdivisions of the Basidiomycota, and represents all of the fungi which form macroscopic fruiting bodies. Agaricomycotina contains over 30,000 species, divided into three classes: Tremellomycetes, Dacrymycetes, and Agaricomycetes. Around 98% of the species are in the class Agaricomycetes, including all the agarics, bracket fungi, clavarioid fungi, corticioid fungi, and gasteroid fungi. Tremellomycetes contains many basidiomycete yeasts and some conspicuous jelly fungi. Dacrymycetes contains a further group of jelly fungi. These taxa are founded on molecular research, based on cladistic analysis of DNA sequences, and supersede earlier morphology-based classifications. Agaricomycotina contains nearly one third of all described species of fungi.
A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae and either Protista or Protozoa and Chromista.
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.
Annulohypoxylon, sometimes called cramp balls, is a genus of fungi in the family Xylariaceae. The 27 species in the genus have a collectively widespread distribution.
Hericium is a genus of edible mushrooms in the family Hericiaceae. Species in this genus are white and fleshy and grow on dead or dying wood; fruiting bodies resemble a mass of fragile icicle-like spines that are suspended from either a branched supporting framework or from a tough, unbranched cushion of tissue. This distinctive structure has earned Hericium species a variety of common names—monkey's head, lion's mane, and bear's head are examples. Taxonomically, this genus was previously placed within the order Aphyllophorales, but recent molecular studies now place it in the Russulales.
Episphaeria is a genus of fungus in the Agaricales. The genus is monotypic, and contains the single rare species Episphaeria fraxinicola, found in Europe. Its familial position is not known with certainty. The tiny fruit bodies of the fungus resemble minute, white cups that grow scattered or in groups on the bark of ash trees.
Guepinia is a genus of fungus in the Auriculariales order. It is a monotypic genus, containing the single species Guepinia helvelloides, commonly known as the apricot jelly. The fungus produces salmon-pink, ear-shaped, gelatinous fruit bodies that grow solitarily or in small tufted groups on soil, usually associated with buried rotting wood. The fruit bodies are 4–10 cm (1.6–3.9 in) tall and up to 17 cm (6.7 in) wide; the stalks are not well-differentiated from the cap. The fungus, although rubbery, is edible, and may be eaten raw with salads, pickled, or candied. It has a white spore deposit, and the oblong to ellipsoid spores measure 9–11 by 5–6 micrometers. The fungus is widely distributed in the Northern Hemisphere, and has also been collected from South America.
Annulohypoxylon archeri is a saprophytic fungus species. It was moved from the genus Hypoxylon into the genus Annulohypoxylon erected in 2005 by Hsieh, Ju and Rogers.
Auricularia auricula-judae, which has the recommended English name jelly ear, also known as Judas's ear or 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; the common name "Judas's ear" was largely eclipsed by the corruption "Jew's ear".
Hypsizygus ulmarius, also known as the elm oyster mushroom, and less commonly as the elm leech, elm Pleurotus, is an edible fungus. It has often been confused with oyster mushrooms in the Pleurotus genus but can be differentiated easily as the gills are either not decurrent or not deeply decurrent. While not quite as common as true oyster mushrooms, they have a wide range globally in temperate forests. The mushrooms and vegetative hyphae of this species have been studied in recent years for their potential benefits to human health, and mycoremediation.
Annulohypoxylon thouarsianum is a species of ascomycete fungus.
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.
Biscogniauxia atropunctata, the hypoxylon canker, is a species of sac fungus in the family Graphostromataceae. Like many other fungi in the genus, it is a plant pathogen; specifically this species can cause Biscogniauxia (Hypoxylon) canker and dieback disease in host trees.
