Hygrophorus Purpurascens
''Hygrophorus purpurascens'', commonly known as the veiled purple hygrophorus, is a species of agaric fungus in the family Hygrophoraceae. Its cap has a pink background color with streaks of purplish red overlaid, and mature gills have red spots. Taxonomy The species was originally described as ''Agaricus purpurascens'' by Johannes Baptista von Albertini and Lewis David de Schweinitz in 1805. Elias Fries transferred it to the genus ''Hygrophorus'' in 1838. Paul Kummer's 1871 ''Limacium purpurascens'' is a synonym. The specific epithet ''purpurascens'' means "becoming purple". It is commonly known as the "veiled purple hygrophorus". Description The cap is convex to flattened, measuring in diameter. The color is pinkish red in the center to white, often irregularly tinged with pink. The flesh is white. The gills have a decurrent attachment to the stipe and are white to pale pink spotted with pinkish or purplish red. The stipe measures long by wide, and is more or less the sa ...

Johannes Baptista Von Albertini
Johannes Baptista von Albertini (17 February 1769 – 6 December 1831) was a German botanist, mycologist and clergyman of the Moravian Church. He was born in the town of Neuwied. He studied theology in Niesky and at the seminary in Barby. During this period he became a friend of Friedrich Schleiermacher (1768–1834), who later became a renowned theologian. In 1796 Albertini became a lecturer at the seminary in Niesky, and in 1804 was a minister in Niesky. In 1814 he was elected bishop, and in 1824 was chairman of the ''Unitätsältestenkonferenz'', the denomination's executive board, in Berthelsdorf. He was a gifted speaker and a highly influential minister, and in 1805 a compilation of his sermons was published as ''30 Predigten für Freunde und Mitglieder der Brüdergemeine'' (Thirty Sermons for Friends and Members of the Moravian Brethren's Church). In the field of mycology he was co-author with Lewis David de Schweinitz (1780–1834) of a work on Upper Lusatian fungi titled ...

Decurrent
''Decurrent'' (sometimes decurring) is a term used in botany and mycology to describe plant or fungal parts that extend downward. In botany, the term is most often applied to leaf blades that partly wrap or have wings around the stem or petiole and extend down along the stem. A "decurrent branching habit" is a plant form common for shrubs and most angiosperm trees, contrasted with the excurrent or "cone-shaped crown" common among many gymnosperms. The decurrent habit is characterized by having weak apical dominance that eventually produces a rounded or spreading tree crown. Examples of trees with decurrent habit are most hardwood trees: oak, hickory, maple, etc.Claud L. Brown, Robert G. McAlpine, Paul P. Kormanik, "Apical Dominance and Form in Woody Plants: A Reappraisal", ''American Journal of Botany'', Vol. 54, No. 2 (February 1967), pp. 153–162, In mycology, the term is most often applied to the hymenophore of a basidiocarp (such as the lamellae or "gills" of a mushroo ...

Fungi Described In 1805
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 fun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MycoBank
MycoBank is an online database, documenting new mycological names and combinations, eventually combined with descriptions and illustrations. It is run by the Westerdijk Fungal Biodiversity Institute in Utrecht. Each novelty, after being screened by nomenclatural experts and found in accordance with the ICN ( International Code of Nomenclature for algae, fungi, and plants), is allocated a unique MycoBank number before the new name has been validly published. This number then can be cited by the naming author in the publication where the new name is being introduced. Only then, this unique number becomes public in the database. By doing so, this system can help solve the problem of knowing which names have been validly published and in which year. MycoBank is linked to other important mycological databases such as ''Index Fungorum'', Life Science Identifiers, Global Biodiversity Information Facility (GBIF) and other databases. MycoBank is one of three nomenclatural repositories r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snowbank Mushroom
A snowbank fungus is any one of a number of diverse species of fungi that occur adjacent to or within melting snow. They are most commonly found in the mountains of western North America where a deep snowpack accumulates during the winter and slowly melts through the spring and summer, often shaded by coniferous forest. They may be saprotrophic, mycorrhizal, or in the case of ''Caloscypha fulgens'', pathogenic. History William Bridge Cooke was the first to discuss the snowbank fungi as a distinct ecological group in 1944 when he discussed the fungal flora of Mount Shasta in California. He followed this with another publication 11 years later. In his 1975 book ''A Field Guide to Western Mushrooms'', Alexander H. Smith discussed what he called the "snowbank flora", noting "It seems obvious to me that the species in this group are well established throughout the forest zone, and have adjusted to this fruiting pattern, possibly as a response to the habitat drying out and warming up ...

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

Hygrophorus Russula
''Hygrophorus russula'', commonly known as the pinkmottle woodwax, false russula and russula-like waxy cap, is a fungus native to North America and Europe. German naturalist Jacob Christian Schäffer described the species as ''Agaricus russula'' in 1774. The species name is derived from its reddish coloration, reminiscent of members of the genus ''Russula''. French botanist Claude Casimir Gillet placed it in the genus ''Tricholoma'' in 1878, before American naturalist Calvin Henry Kauffman transferred it to ''Hygrophorus'' in 1918. Though Kauffman thought it resembled ''Tricholoma'', he held that its waxy gills showed it to be better suited to the genus ''Hygrophorus''. The fruit bodies, or mushrooms, can be abundant some years, especially after rainfall, sometimes appearing in arcs or fairy rings. The cap is hemispherical before flattening out with age, though the cap margin remains inrolled. Reaching in diameter, it has a base colour of white or pink with streaks of pink, wine ...

Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multice ...

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. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...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 ...
