Thallus brown to grey-brown, rugose. Distinguished from similar U. hyperborea by the black lower surface and formation of thalloconidia. On siliceous and volcanic boulders and rocks, mainly in wet habitats, on upper or vertical surfaces, often enriched with nutrients. Typically found in mountain areas, in the Czech Republic known from montane and submontane belts. Rare, found in less than ten localities in the Czech Republic. In central Europe, it is more common in the Alps and the Carpathians.
