Lichenised.

Substrate: calciferous 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 mainly temperate, probably holarctic species found on hard limestone and dolomite in rather shaded and sheltered situations, often on faces seldom wetted by rain; widespread throughout the Alps.
