Lichenised.

Substrate: siliceous rocks

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 widespread, holarctic species found on hard siliceous rocks, including quartz, in sunny-dry situations, often on steeply inclined faces, common only in dry-continental areas, from some parts of the Mediterranean coast to dry valleys of the Alps; the species is chemically variable.
