Metuloidea Tawa
''Metuloidea'' is a genus of five species of fungi in the family Steccherinaceae. The genus was circumscribed by New Zealand-based mycologist Gordon Herriot Cunningham in 1965. The type species is '' M. tawa'', a fungus originally described by Cunningham as a species of '' Trametes''. Formerly classified in family Meruliaceae, ''Metuloidea'' was moved to the Steccherinaceae in 2016, following prior research that outlined a revised framework for the Steccherinaceae based on molecular phylogenetics. Description ''Metuloidea'' contains fungi that produce poroid or hydnoid fruit bodies that are brown and have a sweet odour. It features a dimitic hyphal system with branched, relatively wide skeletal hyphae (3–5 μm). The spores are ellipsoid to cylindrical, thin walled, and measure 3–4 by 2–2.8 μm.

Hydnoid Fungi
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps (fruit bodies) producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus '' Hydnum'' ("hydnoid" means ''Hydnum''-like), but it is now known that not all hydnoid species are closely related. History ''Hydnum'' was one of the original genera created by Linnaeus in his ''Species Plantarum'' of 1753. It contained all species of fungi with fruit bodies bearing pendant, tooth-like projections. Subsequent authors described around 900 species in the genus. With increasing use of the microscope, it became clear that not all tooth fungi were closely related and most ''Hydnum'' species were gradually moved to other genera. The Dutch mycologist Rudolph Arnold Maas Geesteranus paid particular attention to the group, producing a series of papers reviewing the taxonomy of hydnoid fungi. The original genus ''Hydnum ...

Polyporales Genera
The Polyporales are an order of about 1800 species of fungi in the division Basidiomycota. The order includes some (but not all) polypores as well as many corticioid fungi and a few agarics (mainly in the genus ''Lentinus''). Many species within the order are saprotrophic, most of them wood-decay fungus, wood-rotters. Some genera, such as ''Ganoderma'' and ''Fomes'', contain species that attack living tissues and then continue to degrade the wood of their dead hosts. Those of economic importance include several important plant pathology, pathogens of trees and a few species that cause damage by rotting structural timber. Some of the Polyporales are commercially Fungiculture, cultivated and marketed for use as food items or in traditional Chinese medicine. Taxonomy History The order was originally proposed in 1926 by Swiss mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota Basidiomycota () is one of two large divisions that, together with ...

Miles Joseph Berkeley
Miles Joseph Berkeley (1 April 1803 – 30 July 1889) was an English cryptogamist and clergyman, and one of the founders of the science of plant pathology. Life Berkeley was born at Biggin Hall, Benefield, Northamptonshire, and educated at Rugby School and Christ's College, Cambridge. Taking holy orders, he became incumbent of Apethorpe in 1837, and vicar of Sibbertoft, near Market Harborough, in 1868. He acquired an enthusiastic love of cryptogamic botany (lichens) in his early years, and soon was recognized as the leading British authority on fungi and plant pathology. Christ's College made him an honorary fellow in 1883. He was well known as a systematist in mycology with some 6000 species of fungi being credited to him, but his ''Introduction to Cryptogamic Botany'', published in 1857, and his papers on Vegetable Pathology in the ''Gardener's Chronicle'' in 1854 and onwards, show that he had a broad grasp of the whole domain of physiology and morphology as understood in ...

Edward Angus Burt
Edward Angus Burt (April 9, 1859 – April 27, 1939) was an American mycologist and an authority on the resupinate (flat on the substrate) fungus family Thelephoraceae.Farlow Herbarium, Harvard UniversityFarlow Herbarium/ref> He received his M.A. in 1894 and Ph.D. in 1895, both from Harvard University under William G. Farlow and Roland Thaxter. He became Professor of Natural History at Middlebury College in 1895, then both Professor of Botany at the Henry Shaw School of Botany at Washington University and mycologist for the Missouri Botanical Garden in 1913. He also worked on a systematic description of basidiomycetes such as ''Merulius'' and fungi from Vermont, Siberia, and Java. The ''Septobasidium ''Septobasidium'' is a fungal genus within the family Septobasidiaceae. Approximately 175 described species are associated with this genus.

Otto Miettinen
Otto is a masculine German given name and a surname. It originates as an Old High German short form (variants ''Audo'', ''Odo'', '' Udo'') of Germanic names beginning in ''aud-'', an element meaning "wealth, prosperity". The name is recorded from the 7th century ( Odo, son of Uro, courtier of Sigebert III). It was the name of three 10th-century German kings, the first of whom was Otto I the Great, the first Holy Roman Emperor, founder of the Ottonian dynasty. The Gothic form of the prefix was ''auda-'' (as in e.g. '' Audaþius''), the Anglo-Saxon form was ''ead-'' (as in e.g. ''Eadmund''), and the Old Norse form was '' auð-''. The given name Otis arose from an English surname, which was in turn derived from ''Ode'', a variant form of ''Odo, Otto''. Due to Otto von Bismarck, the given name ''Otto'' was strongly associated with the German Empire in the later 19th century. It was comparatively frequently given in the United States (presumably in German American families) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leif Ryvarden
Leif Randulff Ryvarden (born 9 August 1935) is a Norwegian mycologist. Early life and education Leif Ryvarden was born in Bergen as a son of Einar Norberg Johansen (1900–1959) and Hjørdis Randulff (1912–1975). He finished his secondary education at Berg in 1954 and took basic military education from 1957 to 1958 and in 1956 he changed his last name from Johansen to Ryvarden. He studied chemistry at the Norwegian Institute of Technology. In 1961 he ran for election as chairman of Student Society in Trondheim, albeit unsuccessfully. In 1963, he graduated with the siv.ing. degree , and later majored in botany at the University of Oslo, taking a cand.real. degree. He also studied in London from 1971 to 1972, a stay that sparked his interest in mycology. Academic career Ryvarden conducted field work in about eighty countries, mostly in a tropical environment. From 1965 to 1966, he was employed as research assistant at the Norwegian Institute of Technology, from 1966 to 1972 as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellipsoid
An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular axes of symmetry which intersect at a center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal axes'', or simply axes of the ellipsoid. If the three axes have different lengths, the figure is a triaxial ellipsoid (r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidiospore
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 in the ...
