Gyalectaria
''Gyalectaria'' is a genus of crustose lichens in the family Coccotremataceae. It has three species. The genus was circumscribed in 2010 by Imke Schmitt, Klaus Kalb and Helge Thorsten Lumbsch, with '' G. jamesii'' assigned as the type species. The three species transferred to the genus were originally placed in the large genus ''Pertusaria''. Molecular phylogenetics showed that they belong to a lineage distinct from and unrelated to that genus, but with a sister group relationship to the genus ''Coccotrema''. The genus name combines ''Gyalect''- (referring to the morphologically similar genus ''Gyalecta ''Gyalecta'' is a genus of fungi in the family Gyalectaceae that contains 50 species.

Coccotremataceae
The Coccotremataceae are a family of lichen-forming fungi in the order Pertusariales. Species in this widely distributed family grow on bark or rocks, especially in maritime regions. Genera , Species Fungorum accepts 3 genera and 23 species, in the family Coccotremataceae. This is a list of the genera in the Coccotremataceae based on a 2020 review and summary of fungal classification by Wijayawardene and colleagues.

Klaus Kalb
Klaus Kalb (born 1942) is a German lichenologist and an authority on tropical lichens. Biography Klaus Kalb was born in Nuremberg in 1942 and grew up in southern Bavaria. From 1960 to 1965 he studied biology, chemistry, and geography at the University of Erlangen–Nuremberg. Kalb was greatly interested in lichens and decided to pursue a doctoral degree; his thesis work was about lichen communities in the Ötztal Alps. From 1978–1981 he was a teacher at the Colégio Visconde de Porto Seguro in São Paulo, Brazil. This position afforded him the opportunity to initiate research into tropical lichens. Kalb earned his habilitation from the University of Regensburg in 1989, becoming an associate professor with that institution. In 2014, the University of Wisconsin herbarium purchased Kalb's lichen collection of 60,000 specimens for $75,000. With the acquisition of Kalb's collection, rich in tropical and European specimens, the herbarium houses about 70% of the world's ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same ta ...

Taxa Described In 2010
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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pertusariales Genera

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 Fr ...

Coccotrema
''Coccotrema'' is a genus of lichen-forming fungi. It is the type genus of the family Coccotremataceae, in the order Pertusariales. The genus contains 16 species. Taxonomy ''Coccotrema'' was circumscribed by Swiss botanist Johannes Müller Argoviensis in 1889, with ''Coccotrema antarcticum'' assigned as the type species. In a 2001 publication, Schmidt and colleagues showed, using molecular phylogenetics, that the species then known as ''Lepolichen coccophorus'' (the type species of the genus ''Lepolichen'', created by Trevisan in 1853) was nested in a clade that contained ''Coccotrema'' species, and so transferred that species into ''Coccotrema'', as ''Coccotrema coccophorum''. However, the genus ''Lepolichen'' is older than ''Coccotrema'', and so its name has priority according to the rules for botanical nomenclature. To minimize nomenclatural disruption, Alan Fryday and colleagues submitted a proposal to conserve the name ''Coccotrema'' against ''Lepolichen''. Species *'' ...
