Cortinarius Cyanites
''Cortinarius cyanites'' is a basidiomycete fungus of the genus '' Cortinarius'' native to Europe. Elias Magnus Fries described this species in his 1838 book ''Epicrisis Systematis Mycologici seu Synopsis Hymenomycetum'' as ''Cortinarius cyanites''. The species name is derived from the Ancient Greek ''cyanos'' "dark blue" Within the large genus '' Cortinarius'', it is classified in the subgenus ''Phlegmacium'' and section ''Cyanites''. Genetic analysis showed in 2014 that two previously-described species—''C. subcyanites'' and ''C. pseudocyanites''—lay within the concept of ''C. cyanites'', but conversely revealed three distinct lineages, with two new species—'' C. boreicyanites'' and '' C. violaceorubens''—described. The fruitbodies of this fungus have convex caps, with diameters typically in the range , and various shades of violet, brown or grey. They are slimy when young, and later have brown scales. The pale purple stipe is bulbous, in height and in width. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö ( Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fungi Described In 1838
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 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 organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Cortinarius Species
__NOTOC__ The ''cortina'' around the fungi which gives name to the genus. With around 2000 species, '' Cortinarius'' is the biggest genus of fungi that form mushrooms. Apart from a few species such as '' C. caperatus'', many even so-called edible species appear to have very similar species that are at least inedible if not poisonous, or otherwise may differ in edibility geographically.

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer ( American spelling), also commonly known as a 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 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 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 . The longest human chromosome, chromosome 1, is approximately in length.

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 ...

Lamella (mycology)
In mycology, a lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, ''Lactarius'' species typically seep latex from their gills. It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolved gills i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meinhard Michael Moser
Meinhard Michael Moser (13 March 192430 September 2002) was an Austrian mycologist. His work principally concerned the taxonomy, chemistry, and toxicity of the gilled mushrooms (Agaricales), especially those of the genus ''Cortinarius'', and the ecology of ectomycorrhizal relationships. His contributions to the Kleine Kryptogamenflora von Mitteleuropa series of mycological guidebooks were well regarded and widely used. In particular, his 1953 ''Blätter- und Bauchpilze (Agaricales und Gastromycetes)'' 'The Gilled and Gasteroid Fungi (Agaricales and Gastromycetes)'' which became known as simply "Moser", saw several editions in both the original German and in translation. Other important works included a 1960 monograph on the genus ''Phlegmacium'' (now considered part of ''Cortinarius'') and a 1975 study of members of ''Cortinarius'', '' Dermocybe'', and '' Stephanopus'' in South America, co-authored with the mycologist Egon Horak. After showing interest in natural sciences in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp ( fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium ( hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various '' Amanita'' species and boletes. Some, such as the parasol mushroom, have distinct bosses or umbos and are described as '' umbonate''. An umbo is a knobby protrusion at th ...
