Cecidonia Umbonella
''Cecidonia'' is a genus of lichenicolous fungi in the family Lecideaceae. It has two species. The genus was circumscribed in 1988 by Dagmar Triebel and Gerhard Rambold, with '' C. umbonella'' assigned as the 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 ....

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Lichenicolous Fungi
A lichenicolous fungus is a parasitic fungus that only lives on lichen as the host. A lichenicolous fungus is not the same as the fungus that is the component of the lichen, which is known as a lichenized fungus. They are most commonly specific to a given fungus as the host, but they also include a wide range of pathogens, saprotrophs, and commensals. It is estimated there are 3000 species of lichenicolous fungi. More than 1800 species are already described among the Ascomycota and Basidiomycota.Lichenicolous Fungi: Interactions, Evolution, and Biodiversity, Lawrey, James D.; Diederich, Paul. The Bryologist 106(1), pp. 80 120, 2003/ref> More than 95% of lichenicolous fungi described as of 2003 are ascomycetes, in 7 classes and 19 orders. Although basidiomycetes have less than 5% of lichenicolous lichen species, they represent 4 classes and 8 orders. Many lichenicolous species have yet to be assigned a phylogenetic position as of 2003. See also * List of lichenicolous fungi o ...

Lecideaceae
The Lecideaceae are a family of lichens in the order Lecideales (Ascomycota, class Lecanoromycetes). Genera According to a recent (2022) estimate, the Lecideaceae comprise 29 genera and about 260 species. The following list indicates the genus name, the taxonomic authority, year of publication, and the number of species: *'' Amygdalaria'' – 11 spp. *'' Bahianora'' – 1 sp. *'' Bellemerea'' – 10 spp. *'' Bryobilimbia'' – 6 spp. *'' Catarrhospora'' – 2 spp. *'' Cecidonia'' – 2 spp. *'' Clauzadea'' – 7 spp. *'' Cryptodictyon'' – 2 spp. *'' Eremastrella'' – 2 spp. *''Farnoldia'' – 6 spp. *'' Immersaria'' – 8 spp. *'' Koerberiella'' – 2 spp. *'' Labyrintha'' – 1 sp. *''Lecidea'' – ca. 100 spp. *'' Lecidoma'' – 1 sp. *'' Lopacidia'' – 1 sp. *'' Melanolecia'' – 7 spp. *'' Pachyphysis'' – 1 sp. *'' Paraporpidia'' – 3 spp. *'' Poeltiaria'' – 8 spp. *'' Poeltidea'' – 3 spp. *'' Porpidia'' – 51 spp. *'' Porpidinia'' – 2 spp. ...

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 phylogenetics ...

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.
