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
''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] |
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] |

Cryptococcus (fungus)
''Cryptococcus'' is a genus of fungi in the family Cryptococcaceae that includes both yeasts and filamentous species. The filamentous, sexual forms or teleomorphs were formerly classified in the genus ''Filobasidiella'', while ''Cryptococcus'' was reserved for the yeasts. Most yeast species formerly referred to ''Cryptococcus'' have now been placed in different genera. The name ''Cryptococcus'' comes from the Greek for "hidden sphere" (literally "hidden berry"). Some ''Cryptococcus'' species cause a disease called cryptococcosis. Taxonomy The genus was described by French mycologist Jean Paul Vuillemin in 1901, when he failed to find ascospores characteristic of the genus ''Saccharomyces'' in the yeast previously known as ''Saccharomyces neoformans''. Over 300 additional names were subsequently added to the genus, almost all of which were later removed following molecular research based on cladistic analysis of DNA sequences. As a result, some ten species are currently recogniz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuniculitremaceae
The Cuniculitremaceae are a family of fungi in the order Tremellales. There are three genera in the family. ''Sterigmatosporidium polymorphum'' parasitizes other fungi growing in insect galleries in wood. It does not produce basidiocarps (fruit bodies), but has septate basidia similar to those found in the genus ''Tremella''. Most species are known only from their yeast Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom.

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 ...

Tremellomycetes
The Tremellomycetes are a class of dimorphic fungi in the Agaricomycotina. Some species have gelatinous basidiocarps (fruiting bodies) or (microscopically) a sacculate parenthesome. There are six orders, 17 families, and 39 genera in the Tremellomycetes. Tremellomycetes include yeasts, dimorphic taxa, and species that form complex fruiting bodies. Tremellomycetes include some fungi that are human and animal pathogens in the genera ''Cryptococcus'', ''Naganishia'', ''Papiliotrema'', and ''Trichosporon'' and some fungi that are cultivated for food in the genera ''Tremella'' and ''Naematelia ''Naematelia'' is a genus of fungi in the family Naemateliaceae.
