A lichen characterised by shortly elongated pseudocyphellae on the lobe surfaces. It is an arctic-alpine species with a circumpolar distribution, typically found on sun-exposed siliceous rocks and screes. In the Czech Republic, it occurs both above the upper tree line in the most elevated mountains (for example, in the Krkonoše Mts and the Hrubý Jeseník Mts) and under the upper tree line, in suitable rocky habitats in lower mountains and foothills. The species is common, for example, on screes in the Brdy Hill in Central Bohemia.
