Megasporoporia
''Megasporoporia'' is a genus of four species of crust fungi in the family Polyporaceae. The genus is characterized by its large spores (after which it is named), and dextrinoid skeletal hyphae. Taxonomy The genus was circumscribed by mycologists Leif Ryvarden and Jorge Eduardo Wright in 1982, with ''Poria setulosa'' as the type species. They included an additional three species: the new combinations ''M. cavernulosa'' and ''M. hexagonoides'', and the new species ''M. mexicana''. Six new species of ''Megasporoporia'' were introduced by Chinese mycologists between 2004 and 2009 as a result of taxonomic studies of wood-inhabiting fungi in China. Molecular analysis showed that ''Megasporoporia'' nested within the "core polyporoid clade", a grouping of polypore fungi roughly equivalent to a more narrowed but still broad concept of the family Polyporaceae. Later analysis that included the more recently described Chinese species revealed that the genus was not monophyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megasporoporia Minor
''Megasporoporia minor'' is a species of crust fungus in the family Polyporaceae. Found in China, it was described as a new species in 2013 by mycologists Bao-Kai Cui and Hai-Jiao Li. The type was collected was made in Daweishan Forest Park, Yunnan, where it was found growing on a fallen angiosperm branch. It is distinguished from other species of ''Megasporoporia'' by its relatively small pores (number 6–7 per millimetre) and small spores (measuring 6–7.8 by 2.6–4 μm 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 Unit ...); it is these features for which the fungus is named.

Polyporaceae
The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft (as in the case of the dryad's saddle illustrated) to very tough. Most members of this family have their hymenium (fertile layer) in vertical pores on the underside of the caps, but some of them have gills (e.g. ''Panus'') or gill-like structures (such as ''Daedaleopsis'', whose elongated pores form a corky labyrinth). Many species are brackets, but others have a definite stipe – for example, '' Polyporus badius''. Most of these fungi have white spore powder but members of the genus '' Abundisporus'' have colored spores and produce yellowish spore prints. Cystidia are absent. Taxonomy In his 1838 work ''Epicrisis Systematis Mycologici seu Synopsis Hymenomycetum'', Elias Magnus Fries introduced the "Polyporei". August Corda published the name validly the following year, retaining Fries's concept. American mycologist William Alphonso Murrill, ...

Megasporoporiella
''Megasporoporiella'' is a genus of five species of white rot poroid crust fungi in the family Polyporaceae. It was circumscribed in 2013 as a segregate genus of ''Megasporoporia''.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

New Combination
''Combinatio nova'', abbreviated ''comb. nov.'' (sometimes ''n. comb.''), is Latin for "new combination". It is used in taxonomic biology literature when a new name is introduced based on a pre-existing name. The term should not to be confused with ', used for a previously unnamed species. There are three situations: * the taxon is moved to a different genus * an infraspecific taxon is moved to a different species * the rank of the taxon is changed. Examples When an earlier named species is assigned to a different genus, the new genus name is combined with of said species, e.g. when ''Calymmatobacterium granulomatis'' was renamed ''Klebsiella granulomatis'', it was referred to as ''Klebsiella granulomatis comb. nov.'' to denote it was a new combination.

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Fungi
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'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
