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 ...

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 Uni ....

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 "bour ...

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 th ... [...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.

Verrucariales
Verrucariales is an order of 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 (lichen-dwelling) fungi. Phylogenomic analysis suggests that the 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 with certainty into any family. These are: *''Botryolepraria'' – 2 spp. *''Gemmaspora'' – 1 sp. *''Kalbiana'' – 1 sp. *''Merismatium ''Merismatium'' is a genus of lichenicolous ( lichen-dwelling) fungi of uncertain familial placement in the order Verrucariales.

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. The following list shows the families, genera, and number of species in the Chaetothyriales, adapted from a recent (2020) taxonomic and nomenclatural review of the order. *Chaetothyriaceae ::''Actinocymbe'' – 3 spp. ::'' Aithaloderma'' – 12 spp. ::'' Aphanophora'' – 1 sp. ::'' Arthrophiala'' – 1 sp. ::'' Camptophora'' – 2 spp. ::''Ceramothyrium'' – 39 spp. ::'' Ceratocarpia'' – 3 spp. ::'' Chaetothyriomyces'' – 1 sp. ::''Chaetothyrium'' – 67 spp. ::'' Cyphellophoriella'' – 1 sp. ::''Euceramia'' – 3 spp. ::'' Longihyalospora'' – 2 spp. ::''Microcallis'' – 9spp. ::'' Nullicamyces'' – 1 sp. ::''Phaeosaccardinula'' – 41 spp. ::'' Sta ...

Arachnomycetales
''Arachnomyces'' is a genus of cleistothecial ascomycete fungi described in 1902, of which the anamorph (asexual) stage is the genus ''Onychocola''. Although morphologically similar to members of other families, the fungus now belongs to its own monotypic family Arachnomycetaceae, which is the only family in the monotypic order Arachnomycetales. Phylogeny The placement of ''Arachnomyces'' has changed multiple times due to its morphological similarities to members of different families. When first described in 1902, it was included in the old family Perisporiaceae. Later it was considered as part of Onygenaceae, then it was placed within the Gymnoascaceae in 1996. Thanks to phylogenetic analyses ''Arachnomyces'' is currently recognized as a distinct monophyletic lineage, composing its own family Arachnomycetaceae and order Arachnomycetales within the class Eurotiomycetes. Taxonomy There are currently 16 accepted species of ''Arachnomyces''. * '' Arachnomyces bostrychodes'' * '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance ( shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have ta ...

Onygenales
The Onygenales are an order of fungi in the class Eurotiomycetes and division Ascomycota. The order's last common ancestor is estimated to have lived 150 million years ago. Onygenales can consume and break down keratin, the main component of the outer layer of skin. They are primarily found on animals, droppings, and areas frequented by animals. Many are dimorphic, and can change from mold to yeast form depending on their environment. Many onygenalean fungi are pathogens. One species, ''Trichophyton rubrum'', is the primary cause of athlete's foot. This order also includes Coccidioides implicated in Valley fever. The Onygenales are important as emerging human pathogens because of the rising rates of immunosuppression due to live-organ transplant, HIV/AIDS, and autoimmune disorders such as lupus erythematosus Lupus erythematosus is a collection of autoimmune diseases in which the human immune system becomes hyperactive and attacks healthy tissues.

Mycologist
Mycology is the branch of biology concerned with the study of fungi, including their genetic and biochemical properties, their taxonomy and their use to humans, including as a source for tinder, traditional medicine, food, and entheogens, as well as their dangers, such as toxicity or infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz. Beatrix Potter, author of '' The Tale of Peter Rabbit'', also made significant contributions to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
