A small crustose lichen with a grey thallus and inconspicuous, often immersed fruiting bodies, which may or may not contain orange pigments (anthraquinones). The centre of its distribution lies in the Mediterranean and in continental regions of Eurasia. It grows on various types of siliceous rocks, but it strongly prefers basic ones. In the Czech Republic, it is known only from three localities: from serpentinite steppes near Mohelno, from the valley of the river Rokytná close to Ivančice in southern Moravia (Vězda 1978) and from Trubínský vrch in the Křivoklát region.
