Ceriporia Amazonica
''Ceriporia amazonica'' is a species of crust fungus in the family Irpicaceae. Found in Brazil, it was described as new to science in 2014. The fungus is characterized by its salmon-coloured pore surface with angular pores numbering 1–3 per millimetre, and small ellipsoid spores (measuring 2–3 μm) that are among the smallest in genus ''Ceriporia''. The type locality is Amapá National Forest, in the Brazilian Amazon Brazilian commonly refers to: * Something of, from or relating to Brazil * Brazilian Portuguese, the dialect of the Portuguese language used mostly in Brazil * Brazilians, the people (citizens) of Brazil, or of Brazilian descent Brazilian may also ..., for which the species is named.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crust Fungus
The corticioid fungi are a group of fungi in the Basidiomycota typically having effused, smooth basidiocarps (fruit bodies) that are formed on the undersides of dead tree trunks or branches. They are sometimes colloquially called crust fungi or patch fungi. Originally such fungi were referred to the genus '' Corticium'' ("corticioid" means ''Corticium''-like) and subsequently to the family '' Corticiaceae'', but it is now known that all corticioid species are not necessarily closely related. The fact that they look similar is an example of convergent evolution. Since they are often studied as a group, it is convenient to retain the informal (non-taxonomic) name of "corticioid fungi" and this term is frequently used in research papersLarsson K-H, Larsson E, Koljalg U. (2004). High phylogenetic diversity among corticioid homobasidiomycetes. ''Mycological Research'' 108: 983–1002. and other texts.

Irpicaceae
The Irpicaceae are a family of mostly polypores and crust fungi in the order Polyporales. Taxonomy The family was circumscribed in 2003 by mycologists Viacheslav Spirin and Ivan Zmitrovich. The type genus is '' Irpex''. Later multi-gene phylogenetic analyses of the Polyporales supported the use of this family. In these analyses, Irpicaceae is a sister taxon to the Meruliaceae; these two families, as well as the Phanerochaetaceae, form the phlebioid clade. Description Irpicaceae has both polypore and crust fungi. They have a monomitic hyphal system, containing only generative hyphae that do not have clamp connections. Their spores are thin-walled, smooth, and translucent. Cystidia are often absent from the hymenium. More rarely, some species are dimitic and/or with cystidia and/or clamp-connections present; for example, ''Emmia'' and ''Irpex'' have cystidia, and there are clamp connections in ''Gloeoporus''. Irpicaceae fungi produce a white-rot, except for one brown-rot genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmon (color)
Salmon is a range of pinkish-orange to light pink colors, named after the color of salmon flesh. The first recorded use of ''salmon'' as a color name in English was in 1776.Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 203; Color Sample of Salmon: Page 43 Plate 10 Color Sample A7 The actual color of salmon flesh varies from almost white to light orange, depending on their levels of the carotenoid astaxanthin due to how rich a diet of krill and shrimp the fish feeds on; salmon raised on fish farms are given non-synthetic or artificial coloring in their food. __TOC__ Variations of salmon Light salmon resembles the color salmon, but is lighter, not to be confused with dark salmon, which resembles salmon pink but is darker. Salmon pink (or ''salmon'' in Crayola crayons) was introduced by Crayola in 1949. See the List of Crayola crayon colors. Dark salmon resembles the color salmon, but is darker.

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 ellipsoi ... [...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 ...

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 � ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceriporia
''Ceriporia'' is a widely distributed genus of crust fungi. Taxonomy The genus was circumscribed by Dutch mycologist Marinus Anton Donk in 1930, with '' Ceriporia viridans'' as the type species. The generic name combines the Latin word ''cera'' ("wax") and the name ''Poria''. Molecular phylogenetic analyses have shown that ''Ceriporia'' is not monophyletic, despite an earlier study which suggested the contrary. The presence or absence of cystidia is not considered a phylogenetic character in delimiting the species of ''Ceriporia''. Although traditionally classified in the family Phanerochaetaceae, recent molecular phylogenetic analysis supports the placement of ''Ceriporia '' in the Irpicaceae. Species A 2008 estimate placed 22 species in the genus. , Index Fungorum accepts 49 species of ''Ceriporia''. Twenty species occur in China; eighteen species are found in the neotropics. *'' Ceriporia alachuana'' (Murrill) Hallenb. (1979) – Dominican Republic *'' Ceriporia alania'' ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almos ...

Amapá National Forest
The Amapá National Forest ( pt, Floresta Nacional do Amapá) is a national forest in the state of Amapá, Brazil. It supports sustainable exploitation of the natural resources in an area of Amazon rainforest in the Guiana Shield. Location The Amapá National Forest is divided between the municipalities of Pracuúba (52.85%), Ferreira Gomes (44.07%) and Amapá (3.08%) in the state of Amapá. It has an area of . The forest is bounded to the north by the small Mutum River, to the east by the Falsino River, to the west by the Araguari River, and to the south by the confluence of the Falsino and Araguari. In the extreme north there are chains of mountains of significant height, thought to belong to the Tumucumaque complex. To the east it adjoins the Amapá State Forest, a sustainable use environmental unit created in 2006. To the northwest it adjoins the Montanhas do Tumucumaque National Park. Environment The Amapá National Forest is in the Amazon biome. It contains a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
