Lohwagia
''Lohwagia'' is a genus of fungi in the family Phyllachoraceae. The genus was described by Austrian-Czech mycologist Franz Petrak in 1942. ''Lohwagia'' contains three species: the type '' L. intermedia'', '' L. kessleriana'' and '' L. verruciformis''. The genus name of ''Lohwagia'' is in honour of Heinrich Lohwag (1884-1945), who was an Austrian botanist (Mycology), cryptogamen researcher and teacher. He was also the father of botanist and mycologist Kurt Lohwag. The genus was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon.

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogene ...

Kurt Lohwag
Kurt Lohwag (1913–1970) was an Austrian botanist and mycologist. The son of the Austrian mycologist Heinrich Lohwag (1884 - 1945). He was educated at the University of Vienna. For much of his career, he worked at the Hochschule für Bodenkultur, Vienna. He was honoured in 1970, when botanist Franz Petrak named a genus of fungi, '' Lohwagiella'', which is now a synonym of ''Niesslia ''Niesslia'' is a genus of fungi in the family Niessliaceae. It was circumscribed by German mycologist Bernhard Auerswald in 1869, with ''Niesslia chaetomium'' assigned as the type species. These organisms, which are barely visible to the naked ...''

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.

Franz Petrak
Franz Petrak (9 October 1886, Mährisch-Weißkirchen – 9 October 1973, Vienna) was an Austrian-Czech mycologist. From 1906 to 1910, he studied botany at the University of Vienna, where he was a student of Richard Wettstein. In 1913 he obtained his doctorate of sciences, and until 1916, worked as a high school teacher in Vienna. During World War I, he was stationed in Galicia and Albania, where he collected specimens in his spare time. From 1918 to 1938, he worked as a private scientist in his home town, and from 1938 to 1951, was associated with the Naturhistorisches Museum in Vienna. He was the author of nearly 500 published works, primarily in the field of mycology. Much of his mycological work was published in the journal ''Annales mycologici'' and its successor '' Sydowia''. Reportedly, his private herbarium contained 100,000 specimens. As a taxonomist, he described numerous species within the genus '' Cirsium'' (family Asteraceae). The mycological genera of; '' Petr ...

Fungus
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), 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 motility, 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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as '' Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
