Lichenised.

Substrate: calciferous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) 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 cool-temperate species found on steeply inclined to underhanging faces of dolomitic rocks and limestones in rather sheltered situations, mostly in woodlands; widespread throughout the Alps.
