Xanthocarpia
''Xanthocarpia'' is a genus of mostly crustose lichens in the family Teloschistaceae. It has 12 species with a largely Northern Hemisphere distribution. Taxonomy The genus was originally circumscription (taxonomy), circumscribed in 1859 by Abramo Bartolommeo Massalongo and Giuseppe De Notaris, with ''Xanthocarpia ochracea'' as the type species. This species has tetralocular ascospores (i.e. divided into 4 chambers). Description ''Xanthocarpia'' has a thallus that is either crust-like (crustose lichen, crustose) or like a shield or plate attached on the lower surface at a single central point (peltate). In some cases, the thallus is absent; in all cases, a cortex (botany), cortex is absent. The lichen contains anthraquinones compounds. ''Xanthocarpia'' species often have apothecia, which are coloured yellow to orange. These apothecia are zeorine, meaning that the proper exciple (the ring-shaped layer surrounding the hymenium) is enclosed in the thalline exciple. Pycnidia can be p ...

Xanthocarpia Erichansenii
''Xanthocarpia erichansenii'' is a species of terricolous (ground-dwelling), crustose lichen in the family Teloschistaceae. It is found in southwest Greenland, where it grows on loess (a type of soil) among mosses. Taxonomy The lichen was first formally described in 2009 by the lichenologists Sergey Kondratyuk, Arne Thell, Ingvar Kärnefelt, and John Elix; it was initially classified in the genus ''Caloplaca''. The species epithet honours the Danish lichenologist Eric Steen Hansen, who, according to the authors, "has made enormous contributions to our knowledge of lichens in Greenland". Patrik Frödén and colleagues transferred the taxon to the genus ''Xanthocarpia'' in 2013. Description ''Xanthocarpia erichansenii'' features a thallus that typically measures between 3 and 15 mm in width. The thallus is generally composed of tiny, scattered that are convex in shape and range from yellow to a dull yellow-orange colour. These areoles are mostly rounded, varying in size ...

Xanthocarpia Crenulatella
''Xanthocarpia crenulatella'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Taxonomy The species was first formally described by William Nylander in 1886, as a member of genus ''Lecanora''. Henri Olivier transferred it to the genus ''Caloplaca'' in 1909, and it was generally known as this name for more than a century. In 2013, Arup and colleagues transferred the taxon to genus ''Xanthocarpia'' based on a molecular phylogenetics-led restructuring of the family Teloschistaceae. Jan Vondrák and colleagues have suggested that ''Xanthocarpia crenulatella'' may represent an assemblage of microspecies In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each oth ..., "because it is phenotypically quite heterogenous and other species have been describe ...

Xanthocarpia Feracissima
''Xanthocarpia feracissima'' is a species of saxicolous, crustose lichen in the family Teloschistaceae. It was first formally described as a new species in 1953 by Swedish lichenologist Adolf Hugo Magnusson, as a member of the genus ''Caloplaca''. The type specimen was collected in 1939 by John Walter Thomson in Lake Koshkonong, Wisconsin. In the original description, Magnusson notes a similarity to the lichen now known as '' Gyalolechia flavovirescens'', but distinguishes the new species by its lack of a visible thallus, the sordid-reddish color of its , and the "unusually narrow" septa of the spores. Patrik Frödén, Ulf Arup, and Ulrik Søchting transferred the taxon to ''Xanthocarpia'' in 2013, following molecular phylogenetic analysis of the family Teloschistaceae. The lichen occurs in the eastern United States and Canada. In North America, a common name for the species is "sidewalk firedot lichen". It is very common on cement and mortar, particularly on sidewalks that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xanthocarpia Jerramungupensis
''Xanthocarpia jerramungupensis'' is a species of terricolous (ground-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk, Ingvar Kärnefelt, and John Elix; they classified it in the genus ''Caloplaca''. The type specimen was collected from Jerramungup, Western Australia, where it was found growing among scrub on sandy soil. The species epithet refers to the type locality, which, at the time of its original publication, was the only known location of this lichen. Kondratyuk and colleagues transferred the taxon to the genus ''Xanthocarpia'' in 2013, as part of comprehensive molecular phylogenetics Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to ...-led restructuring of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
