Xanthocarpia is a genus of mostly crustose lichens in the family Teloschistaceae.[1] It has 12 species with a largely Northern Hemisphere distribution.

Taxonomy

[edit]

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]

Description

[edit]

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]

Species

[edit]

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]

Xanthocarpia feracissima
