Lichenised.

Substrate: calciferous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a temperate to southern boreal-montane lichen found in rock fissures, on vertical or underhanging surfaces of calcareous rocks, often in woodlands, with a wide altitudinal range; widespread throughout the Alps.
