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 ...

Cyanolichen
Cyanolichens are lichens that apart from the basic fungal component ("mycobiont"), contain cyanobacteria, otherwise known as blue-green algae, as the photosynthesizing component ("photobiont"). Overall, about a third of lichen photobionts are cyanobacteria and the other two thirds are green algae. Some lichens contain both green algae and cyanobacteria apart from the fungal component, in which case they are called "tripartite". Normally the photobiont occupies an extensive layer covering much of the thallus, but in tripartite lichens, the cyanobacterium component may be enclosed in pustule-like outgrowths of the main thallus called cephalodia, which can take many forms. Apart from gaining energy through photosynthesis, the cyanobacteria which live in cephalodia may perform nitrogen fixation on behalf of the lichen community. These cyanobacteria are generally more rich in nitrogen-fixing cells called heterocyst Heterocysts or heterocytes are specialized nitrogen-fixing cells ...

Pannariaceae
The Pannariaceae are a family of lichens in the order Peltigerales (suborder Collematineae). Species from this family have a widespread distribution, but are especially prevalent in southern temperate regions. Genera According to a recent (2020) estimate, the family contains 27 genera and about 360 species. The following list indicates the genus name, the taxonomic authority, year of publication, and the number of species: *'' Atrophysma'' – 1 sp. *'' Austrella'' – 3 spp. *'' Austroparmeliella'' – 5 spp. *''Degelia'' – 16 spp. *'' Erioderma'' – 32 spp. *'' Fuscoderma'' – 5 spp. *''Fuscopannaria'' – 58 spp. *'' Kroswia'' – 4 spp. *'' Gibbosporina'' – 13 spp. *'' Homothecium'' – 4 spp. *'' Joergensenia'' – 1 sp. *'' Leciophysma'' – 2 spp. *'' Leightoniella'' – 1 sp. *'' Leioderma'' – 7 spp. *'' Lepidocollema'' – 22 spp. *'' Leptogidium'' – 3 spp. *''Nebularia'' – 2 spp. *'' Nevesia'' – 1 sp. *''Pannaria'' – ca. 40 spp. *''P ...

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 ...

Abramo Bartolommeo Massalongo
Abramo Bartolommeo Massalongo (13 May 1824 – 25 May 1860) was an Italian paleobotanist and lichenologist. He was born in Tregnago in the Province of Verona and took a great interest in botany as a young man. Massalongo joined the faculty of medicine at the University of Padua in 1844.Cappelletii, Maurizia Alippi (2008)"Abramo Bartolomeo Massalongo"(in Italian). ''Dizionario Biografico degli Italiani, Volume 71''. Retrieved 7 October 2012. Along with Gustav Wilhelm Körber, he founded the "Italian-Silesian" school of lichenology. He also collaborated with Martino Anzi. He was the husband of Maria Colognato and the father of hepaticologist Caro Benigno Massalongo. He also worked in the scientific field of herpetology. In 1859 his ''Catalogo dei rettili delle province venete'' was published in Venice. Massalongo died in Verona in 1860. He was honoured in 1855, when German lichenologist Gustav Wilhelm Körber circumscribed '' Massalongia'' which is a genus of lichen-forming fungi ...

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.
