Arthoniaceae
The Arthoniaceae are a family of lichenized, lichenicolous and saprobic fungi in the order Arthoniales. The Arthoniaceae is the largest family of Arthoniales, with around 800 species. Most species in Arthoniaceae belong in '' Arthonia'' which is the largest genus with 500 species. The second and third largest genus is '' Arthothelium'' with 80 species, and ''Cryptothecia'' with 60 species. ''Arthonia'' is the type genus of Arthoniaceae, and it is known to be a polyphyletic and paraphyletic genus. The process of splitting ''Arthonia'' into monophyletic groups is an ongoing process. In order to make ''Arthonia'' monophyletic, several genera have been described or resurrected. Distribution The species in Arthoniaceae have a worldwide distribution, but are especially prevalent in tropical areas with a Mediterranean climate. They are known from arctic to tropical latitudes, as well as variating altitudes from sea level to alpine regions, distributed in both humid forests and dry habit ...

Arthoniomycetes
Arthoniomycetes are a class of ascomycete fungi. It includes two orders: Arthoniales and Lichenostigmatales. Most of the taxa in these orders are tropical and subtropical lichens. Systematics Phylogenetic analysis supports the monophyly of this class. Dothideomycetes is a sister group. Characteristics Taxa have apothecia, cup- or saucer- shaped ascoma in which the hymenium The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some ... is exposed at maturity. These apothecia are bitunicate - with clearly differentiated inner and outer walls. References Fungus classes Lichen classes Taxa described in 1997 {{Arthoniomycetes-stub ...

Taxa Named By Gustav Wilhelm Körber
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
