Catapyrenium cinereum (Pers.) Körb.

Catapyrenium cinereum is characterized by a white-pruinose squamulose adnate thallus with a black lower cortex, which can usually be seen as a black margin of the areoles. It is a boreal-montane to arctic-alpine circumpolar species, growing on relic stands even at lower elevations. It is usually found on bare calcareous soil, humus and bryophytes in open stands. It used to be recorded at various localities in the Czech Republic in the past, but the records require revision. A part of the historical records was revised by Breuss (1990) and the species was confirmed from the Mt Sněžka in the Krkonoše Mts, near Chrudim and Žďár nad Sázavou. Recently, it has been collected near Vilémovice in the Moravský kras (Moravian karst) and there is an unverified record from Špraněk in the Litovelské Pomoraví region.
