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 ...
