Tremellaceae
The Tremellaceae are a family of fungi in the order Tremellales. The family is cosmopolitan and contains both teleomorphic and anamorphic species, most of the latter being yeasts. All teleomorphs in the Tremellaceae are parasites of other fungi, though the yeast states are widespread and not restricted to hosts. Basidiocarps (fruit bodies), when produced, are gelatinous. The family currently comprises the single genus ''Tremella'', containing around 40 species. The name previously covered a much wider range of genera within the Tremellales, but molecular research, based on cladistic analysis of DNA sequences, now places these genera in separate families. History Fries created the family Tremellaceae (as 'Tremellini') in 1821, basing it on the macromorphology of fruit bodies. He included within it most species of fungi that were gelatinous, dividing it into the genera ''Agyrium'', '' Dacrymyces'', ''Exidia'', ''Hymenella'', ''Naematelia'', and ''Tremella''. ''Agyrium'' and ''H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tremella
''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 (fruit bodies), when produced, are gelatinous and are colloquially classed among the "jelly fungi". Over 100 species of ''Tremella'' (in its wide sense) are currently recognized worldwide. One species, ''Tremella fuciformis'', is commercially cultivated for food. Taxonomy History ''Tremella'' was one of the original genera created by Linnaeus in his ''Species Plantarum'' of 1753. The name comes from the Latin ''tremere'' meaning "to tremble". Linnaeus placed ''Tremella'' in the algae, including within it a variety of gelatinous growths, including seaweeds, cyanobacteria, and myxomycetes, as well as fungi. Subsequent authors added additional species to this mix, until Persoon revised ''Tremella'' in 1794 and 1801, repositioning the genus within the fungi. Persoon's reinterpretation of ''Tremella'' was sufficient ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tremellales
The Tremellales are an order of fungi in the class Tremellomycetes. The order contains both teleomorphic and anamorphic species, most of the latter being yeasts. All teleomorphic species in the Tremellales are parasites of other fungi, though the yeast states are widespread and not restricted to hosts. Basidiocarps (fruit bodies), when produced, are gelatinous. The order currently comprises 11 families, containing around 250 valid species. Significant genera include ''Tremella'', one species of which is edible and commercially cultivated, and the yeast genus ''Cryptococcus'', several species of which are human pathogens. History The order Tremellales was created (as 'Tremellinae') by Swedish mycologist Elias Magnus Fries in 1821 for fungi having gelatinous fruit bodies. it was amended in 1922 by English mycologist Carleton Rea to include all species, gelatinous or not, in which the basidia were "tremelloid" (globose to ellipsoid with vertical or diagonal septa). Rea placed withi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tremella Fuciformis
''Tremella fuciformis'' is a species of fungus; it produces white, frond-like, gelatinous basidiocarps (fruiting bodies). 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. ''Tremella fuciformis'' is commonly known as snow fungus, snow ear, silver ear fungus, white jelly mushroom, and white cloud ears. ''Tremella fuciformis'' is a parasitic yeast, and grows as a slimy, mucus-like film until it encounters its preferred hosts, various species of '' Annulohypoxylon'' (or possibly ''Hypoxylon'') fungi, whereupon it then invades, triggering the aggressive mycelial growth required to form the fruiting bodies. Taxonomy and naming ''Tremella fuciformis'' was first described in 1856 by English mycologist Miles Joseph Berkeley, based on collections made in Brazil by the botanist and explorer Richard Spruce. In 1939, Ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sebacina
''Sebacina'' is a genus of fungi in the family Sebacinaceae. Its species are mycorrhizal, forming a range of associations with trees and other plants. Basidiocarps (fruit bodies) are produced on soil and litter, sometimes partly encrusting stems of living plants. The fruit bodies are cartilaginous to rubbery-gelatinous and variously effused (corticioid) to coral-shaped ( clavarioid). The genus has a cosmopolitan distribution. Taxonomy History The genus was first published in 1871 by Louis and Charles Tulasne who had discovered that two species (''Sebacina incrustans'' and ''Sebacina epigaea'') previously referred to '' Corticium'' or ''Thelephora'' possessed septate basidia, similar to those found in the genus ''Tremella''. Although it was unusual at that time to separate fungal genera on purely microscopic characters, ''Sebacina'' was erected for effused, ''Corticium''-like fungi with tremelloid basidia. Subsequent authors added many additional species of corticioid fungi with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guepinia
''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 tall and up to 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. Taxonomy The species was first described and illustrated as ''Tremella rufa'' by Nicolaus Joseph von Jacquin in 1778. Elias Magnus Fries later (1828) called it ''Guepinia helvelloides'' in his ''Elenchus Fungorum'', based on Augustin P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Protomerulius
''Protomerulius'' is a genus of fungi in the order Auriculariales. Basidiocarps (fruit bodies) are formed on dead wood and have an effused, smooth, spiny, or poroid hymenium. The genus is cosmopolitan. Taxonomy The genus was originally described from Brazil to accommodate a fungus that resembled a polypore but microscopically had septate basidia. The genus name was subsequently extended to include other fungi with a similar combination of features. Molecular research, based on cladistic analysis of DNA sequences, has shown, however, that the type species of ''Protomerulius'', ''P. brasiliensis'' (a synonym of ''P. substuppeus'') is not closely related to most other poroid species with septate basidia, some of which are now placed in the genera '' Aporpium'', '' Elmerina'', and ''Protodaedalea ''Protodaedalea'' is a genus of fungi in the family Auriculariaceae.

Heterochaete
''Heterochaete'' is a genus of fungi in the order Auriculariales. Species produce effused, gelatinous, waxy, or leathery basidiocarps (fruit bodies) on wood, partly or wholly covered in small sterile spines or pegs. The presence of these sterile spines distinguishes the genus from ''Exidiopsis'', species of which are microscopically similar but have smooth basidiocarps. ''Heterochaete'' was monographed by Bodman in 1952 who accepted some 29 species worldwide, most of them from the tropics and subtropics. On the basis of morphological differences, Bodman considered the genus to be heterogeneous and this has been confirmed by molecular research, based on cladistic analysis of DNA sequences. As a result, several species previously placed in ''Heterochaete'' have now been referred to the genera '' Crystallodon'', '' Eichleriella'', '' Heteroradulum'', '' Hirneolina'', '' Metulochaete'', and ''Tremellochaete''. DNA research has also indicated that the type species In zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holtermannia
''Holtermannia'' is a genus of fungi in the order Holtermanniales. Species produce groups of horn-like gelatinous basidiocarps (fruit bodies) on wood and have associated yeast states. The genus is distributed in southeast Asia and Brazil, and contains six species. The genus name of ''Holtermannia'' is in honour of Carl Holtermann (1866 - 1923) (Norwegian-)German botanist (Mycology) and Professor of Botany at the University of Berlin. The genus was circumscribed by Pier Andrea Saccardo and Giovanni Battista Traverso in Syll. Fung. vol.19 on page 871 in 1910. Species known According to GBIF The Global Biodiversity Information Facility (GBIF) is an international organisation that focuses on making scientific data on biodiversity available via the Internet using web services.

Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multice ...

Narcisse Théophile Patouillard
Narcisse Théophile Patouillard (2 July 1854 – 30 March 1926) was a French pharmacist and mycologist. He was born in Macornay, a town in the department of Jura (department), Jura. He studied in Besançon, then furthered his education at the École Supérieure de Pharmacie in Paris, where in 1884 he earned a diploma with a doctoral thesis involving the structure and classification of Hymenomycetes called "''Des Hyménomycètes au point de vue de leur structure et de leur classification''". Des Hyménomycètes au point de vue de leur structure et leur classification Patouillard was a practicing pharmacist for more than forty years, first in Poligny, Jura, Poligny (1881–84), and later in Fontenay-sous-Bois (1884–85), Paris (1886–1898) and Neuilly-sur-Seine (beginning in 1 ...
