TaxonomyEdit

The genus was originally 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).[2]

DescriptionEdit

Xanthocarpia has a thallus that is either crust-like (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 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 present or absent; the conidia have a bacilliform to narrowly ellipsoid shape.[2]

SpeciesEdit

Most Flavoplaca species occur in the Northern Hemisphere. Several are found in southeastern Europe, with a collective distribution extending from the Mediterranean to the Arctic.[2] As of April 2021, Species Fungorum accepts 12 species of Xanthocarpia:[3]
