A crustose lichen with endolithic or thin epilithic, pinkish thallus and black perithecia. In the Czech Republic, it occurs in karst regions, on natural, shaded calcareous and dolomitic rocks. Furthermore, it has been reported from calcareous sandstones or from calcareous insertions within siliceous rocks. It is one of the rather rare lichens in the country, since it is limited by the number of suitable habitats. However, in Europe, the species is locally common, above all in the southern part.
