Bullera
''Bullera'' is a genus of fungi in the family (biology), family Bulleraceae. The genus, which comprises both Teleomorph, anamorph and holomorph, anamorphic and Teleomorph, anamorph and holomorph, teleomorphic forms, formerly contained some 35 species. Molecular phylogenetics, Molecular research, based on cladistic analysis of DNA sequences, has however assigned most of these species elsewhere and reduced the genus ''Bullera'' to just four species. Anamorphic forms are yeasts; teleomorphic forms (formerly referred to ''Bulleromyces'') produce septate basidia resembling those of ''Tremella'' species, but are not known to produce basidiocarps (fruit bodies). The genus name of ''Bullera'' is in honour of Arthur Henry Reginald Buller (1874–1944), a British-Canadian mycologist. References External links * Tremellomycetes {{Agaricomycotina-stub ...

Pseudotremella
''Pseudotremella'' is a genus of fungi in the family Bulleraceae. All ''Pseudotremella'' species are parasites of other fungi and produce anamorphic yeast states. Basidiocarps (fruit bodies), when produced, are gelatinous and are colloquially classed among the "jelly fungi". Four species of ''Pseudotremella'' are currently recognized worldwide. Two of these species are, as yet, only known from their yeast states. Taxonomy History Molecular research, based on cladistic analysis of DNA sequences, has shown that ''Tremella'' is polyphyletic (and hence artificial). In 2017 the new genus ''Pseudotremella'' was proposed to accommodate a group of species that resemble ''Tremella'' species morphologically, but are only distantly related to the latter genus. Description Fruit bodies (when present) are gelatinous, white to amber or violet, and pustular to cephaliform (like a brain, with folds and ridges). Microscopic characters ''Pseudotremella'' species produce hyphae that are typical ... [...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).

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] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Basidiocarp
In fungi, a basidiocarp, basidiome, or basidioma () is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye (especially those with a more or less agaricoid morphology) are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles. Structure All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi. In more complex basidiocarps, there is differentiation into a stipe, a pileus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yeast
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species. Yeasts are unicellular organisms that evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae. Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 µm in diameter, although some yeasts can grow to 40 µm in size. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other conditions) are ca ...

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. All ''Naematelia'' species are parasites of other fungi (''Stereum'' species) and produce anamorphic yeast states. Basidiocarps (fruit bodies), when produced, are gelatinous and ar ...''.
