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 probably holarctic, subtropical to boreal-montane, very polymorphic lichen found on a wide variety of calciferous substrata wetted by rain; widespread throughout the Alps.
