Tremella Globispora
''Tremella globispora'' is a species of fungus in the family Tremellaceae. It produces hyaline, pustular, gelatinous basidiocarps (fruit bodies) and is parasitic on pyrenomycetous fungi (''Diaporthe'' species) on dead herbaceous stems and wood. It was originally described from England. Taxonomy The species was formerly referred to ''Tremella tubercularia'', a nomen novum proposed by Miles Joseph Berkeley when transferring his earlier ''Tubercularia albida'' to the genus ''Tremella'' (to avoid creating a homonym of ''Tremella albida'' Huds.). In 1970, examination of Berkeley's original collections by English mycologist Derek Reid showed, however, that ''Tremella tubercularia'' is a gelatinous ascomycete, now known as '' Ascocoryne albida''. Reid therefore described ''Tremella globispora'' (as "T. globospora") to accommodate the genuine ''Tremella'' species that had previously and mistakenly been referred to ''T. tubercularia''. The type collection from Sussex was on perithec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derek Reid
Derek Agutter Reid (2 September 1927 – 18 January 2006) was an English mycologist. Background and education Reid was born in Leighton Buzzard, Bedfordshire, the son of a picture-framer. He was educated at Cedars School and the University of Hull, where he studied geology and botany. He gained his PhD from the University of London in 1964, for a thesis (later published) on stipitate stereoid fungi. Mycological career and travels In 1951, he became assistant to Dr R.W.G. Dennis, head of mycology at the Royal Botanic Gardens, Kew. On his retirement in 1975, Derek Reid took over his position and remained at Kew till his own retirement in 1987. Derek Reid was a naturalist and enthusiastic field mycologist, leading regular fungus forays in his native Bedfordshire for over 40 years, as well as tutoring fungus identification courses at Field Studies Centres, and evening classes at the University of London. He published the popular field guide to British fungi; Mushrooms and Toa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Tremella Colpomaticola
''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 sufficien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nitschkia Grevillei
''Niesslia'' is a genus of fungi in the family Niessliaceae. It was circumscribed by German mycologist Bernhard Auerswald in 1869, with '' Niesslia chaetomium'' assigned as the type species. These organisms, which are barely visible to the naked eye, are found in decaying plant matter and are parasites of lichens, other fungi, or nematode eggs. They belong to the ascomycetes and in their teleomorphic (sexual) stage they form distinctive dark brown shiny fruiting bodies with spines. The fruiting body structures are a flask-shaped type called perithecia where the spores escape through ostioles. The asexual anamorphic stage was given the genus name ''Monocillium'', now considered a synonym. Description ''Niesslia'' is a genus of small, dark-coloured fungi that typically grow on decaying plant material. These fungi produce distinctive reproductive structures called perithecia, which are visible to the naked eye as tiny, dark spots on the plant surface. The perithecia of ''Nie ...

Basidiospores
A basidiospore is a reproductive spore produced by basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration i ...

Micrometre
The micrometre (English in the Commonwealth of Nations, Commonwealth English as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI Unit, SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cell (biology), cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of str ...

Basidia
A basidium (: basidia) is a microscopic spore-producing structure found on the hymenophore of reproductive bodies of basidiomycete fungi. The presence of basidia is one of the main characteristic features of the group. These bodies are also called tertiary mycelia, which are highly coiled versions of secondary mycelia. A basidium usually bears four sexual spores called basidiospores. Occasionally the number may be two or even eight. Each reproductive spore is produced at the tip of a narrow prong or horn called a sterigma (), and is forcefully expelled at full growth. The word ''basidium'' literally means "little pedestal". This is the way the basidium supports the spores. However, some biologists suggest that the structure looks more like a club. A partially grown basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but some have ones with many cells (a phragmobasidia). For instance, rust fungi in the order ''Puccinal ...
