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 taxon containing xanthones in the cortex and therefore of a distinctly yellowish colour; in the Alps it is common only in dry situations, such as on south-exposed faces.
