Eurotiomycetes Genera

	Eurotiomycetes Genera Eurotiomycetes is a large class of ascomycetes with cleistothecial ascocarps within the subphylum Pezizomycotina, currently containing around 3810 species according to the Catalogue of Life. It is the third largest lichenized class, with more than 1200 lichen species that are mostly bitunicate in the formation of asci. It contains most of the fungi previously known morphologically as "Plectomycetes". Systematics and phylogeny Internal relationships The class Eurotiomycetes was circumscribed in 1997 by Swedish mycologists Ove Erik Eriksson and Katarina Winka. At that time it only contained the order Eurotiales, which together with the next order added, Onygenales, form a monophyletic group comprising most of the fungi in "Plectomycetes", a group no longer in use that unified fungi under exclusively morphological characteristics. As more orders were added to Eurotiomycetes, the first two along with Arachnomycetales became constrained to the first subclass, Eurotiomycetidae. In 2 ...

	Verrucaria Nigrescens ''Verrucaria nigrescens'' is a widespread species of crustose lichen in the family Verrucariaceae. It was first formally described as a new species by Christiaan Hendrik Persoon in 1795. The lichen produces a very dark brown thallus that grows on rocks; the medulla is black. There are black perithecia that resemble buried dots, and which measure 0.15–0.3 mm in diameter. Ascospores measure 14–24 by 7–11 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 ....

picture info	Ascus An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. '' Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. '' Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some '' Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bou ...

picture info	Taxon 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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Pyrenulales The ''Pyrenulales'' are an order of ascomycetous fungi within the class Eurotiomycetes and within the subphylum Pezizomycotina. Taxonomy As of 2022 the order contains one family, 14 genera and around 296 species.

Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of ... [...More Info...] [...Related Items...] OR:* [Wikipedia] [Google] [Baidu]
	Verrucariales Verrucariales is an order (biology), order of Ascomycota, ascomycetous fungi within the subclass Chaetothyriomycetidae of the class Eurotiomycetes. Although most of the Verrucariales are lichenised, the family Sarcopyreniaceae consists of 11 species of lichenicolous fungi, lichenicolous (lichen-dwelling) fungi. Phylogenomics, Phylogenomic analysis suggests that the divergent evolution, divergence between the lichenized Verrucariales and nonlichenized Chaetothyriales occurred about 131 million years ago. Genera of uncertain placement There are some genera in the Verrucariales that have not been placed incertae sedis, with certainty into any family. These are: ''Botryolepraria'' – 2 spp. ''Gemmaspora'' – 1 sp. ''Kalbiana'' – 1 sp. ''Merismatium'' – 10 spp. References Verrucariales, Ascomycota orders Lichen orders Taxa named by David Leslie Hawksworth {{Eurotiomycetes-stub ...

	Chaetothyriales The Chaetothyriales are an order of ascomycetous fungi in the class Eurotiomycetes and within the subclass Chaetothyriomycetidae. The order was circumscribed in 1987 by mycologist Margaret Elizabeth Barr-Bigelow. Families and genera , Species Fungorum includes 9 families, 97 genera, and 691 species in the Chaetothyriales.
