Phaeotremella Translucens
''Phaeotremella translucens'' is a species of fungus in the family Phaeotremellaceae. It produces small, pustular, gelatinous basidiocarps (fruit bodies) and is parasitic on ascocarps of '' Lophodermium '' species on decaying pine needles. It was originally described from Scotland. Taxonomy ''Tremella translucens'' was first published in 1938 by mycologist Hugh Douglas Gordon based on collections from Scotland on decaying pine needles. British mycologist David Minter recollected specimens in Scotland in the 1970s and established that ''Tremella translucens'' was associated with ascocarps of '' Lophodermium '' species, transferring the species to the genus ''Pseudostypella'' based on morphological characters. American mycologist Robert Joseph Bandoni later transferred the species to his new genus ''Sirotrema''. Molecular research, based on cladistic analysis of DNA sequences, has however shown that ''Tremella translucens'' belongs in the genus ''Phaeotremella''. Description Fr ...

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 with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidiomycota
Basidiomycota () is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. Members are known as basidiomycetes. More specifically, Basidiomycota includes these groups: agarics, puffballs, stinkhorns, bracket fungi, other polypores, jelly fungi, boletes, chanterelles, earth stars, smuts, bunts, rusts, mirror yeasts, and '' Cryptococcus'', the human pathogenic yeast. Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores. However, some Basidiomycota are obligate asexual reproducers. Basidiomycota that reproduce asexually (discussed below) can typically be recognized as members of this division by gross similarity to others, by ...

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''.

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''.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of the Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small; they usually differ only in the amount of precipitation. In temperate climates, not only do latitude, latitudinal positions influence temperature changes, but various sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistence of frost. However, some adaptations of Köppen set the minimum at . Continental climate, Continental climates are classified as D and considered to be varie ...
