Polypus
''Polypus'' is a fungal genus of uncertain familial placement in the order Russulales. A monotypic genus, it contains the single species ''Polypus dispansus'', originally described by Curtis Gates Lloyd in 1912 as a species of ''Polyporus''. ''Polypus'' was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius. Not every polyg ... by Serge Audet in 2010.

Russulales
The Russulales are an order of the Agaricomycetes, (which include the agaric genera ''Russula'' and '' Lactarius'' and their polyporoid and corticioid relatives). According to the ''Dictionary of the Fungi'' (10th edition, 2008), the order consists of 12 families, 80 genera, and 1767 species. According to ''Species Fungorum'' (January 2016), the order contains 13 families, 117 genera (16 not assigned to a family), and 3,060 species. Russuloid agarics represent an independent evolutionary line of agarics, not directly related to the Agaricales. This group also includes a number of russuloid hypogeous fungi, polypores such as ''Bondarzewia'', some tooth fungi (e.g. '' Auriscalpium vulgare''), and club fungi e.g. '' Artomyces''. Basidiospores in this group are typically ornamented with amyloid warts or reticulation but a few exceptions are known, e.g. '' Heterobasidion annosum''. The genus ''Clavicorona'' was often treated in the Russulales, but its type species, '' C. taxop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albatrellus Ovinus
''Albatrellus ovinus'' (commonly known as Sheep Polypore) is a terrestrial polypore fungus found in western North America, and Northern Europe. It is very closely related to the rarer '' A. subrubescens'', from which it may be distinguished microscopically by the amyloid spore wall. It is edible and sold commercially in Finland. Description The cap is 4–20 cm wide, convex then flat or depressed, and white then tan or pinkish. The surface is dry and smooth but cracks with age. The whitish stalk is 3–10 cm tall and 1–4 cm wide, perhaps branching, with an equal or larger base. The species may be edible if cooked, but is not recommended by some guides. Similar species A fuller discussion of the small color differences from the inedible ''Albatrellus subrubescens'' can be found at that extensive article. Microscopically, the spores of ''A. subrubescens'' are amyloid, while the ones of ''A. ovinus'' are not.J. Breitenbach, F. Kranzlin, 1986: Pilze der Schweiz, Band 2. Nichtbl ...

Curtis Gates Lloyd
Curtis Gates Lloyd (July 17, 1859 – November 11, 1926) was an American mycologist known for both his research on the gasteroid and polypore fungi, as well as his controversial views on naming conventions in taxonomy. He had a herbarium with about 60,000 fungal specimens, and described over a thousand new species of fungi. Along with his two brothers John Uri Lloyd and Nelson Ashley Lloyd, he founded the Lloyd Library and Museum in Cincinnati. Early life Born on July 17, 1859 in Florence, Kentucky, Curtis Gates Lloyd was the third son of Nelson Marvin and Sophia Webster Lloyd. He and his family moved to Crittenden, Kentucky, in 1867, where Lloyd lived until he was 18. He moved to Cincinnati and was employed as an apprentice in Johnson's pharmacy. This was where he met Dr. John King, physician and editor of the ''American Dispensatory''; the close friendship they formed helped to fuel Lloyd's interest in botany. Lloyd earned his pharmacy certificate while working at the pharmac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

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] |
Polyporus
''Polyporus'' is a genus of poroid fungi in the family Polyporaceae. Taxonomy Italian botanist Pier Antonio Micheli introduced the genus in 1729 to include 14 species featuring fruit bodies with centrally-placed stipes, and pores on the underside of the cap. The generic name combines the Ancient Greek words ("many") and ("pore"). Elias Fries divided ''Polyporus'' into three subgenera in his 1855 work ''Novae Symbol Mycologici'': ''Eupolyporus'', ''Fomes'', and ''Poria''. In a 1995 monograph, Maria Núñez and Leif Ryvarden grouped 32 ''Polyporus'' species into 6 morphologically-based infrageneric groups: ''Admirabilis'', ''Dendropolyporus'', ''Favolus'', ''Polyporellus'', ''Melanopus'', and ''Polyporus'' ''sensu stricto''. The identity of the type species of ''Polyporus'' has long been a matter of contention among mycologists. Some have preferred '' P. brumalis'', some '' P. squamosus'', while others have preferred '' P. tuberaster''. Several molecular phylo ...
