Lichenised.

Substrate: bark, lignum

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, temperate to boreal-montane lichen found on smooth bark of deciduous trees and shrubs in rather humid, well-lit situations, more rarely on wood, with optimum in the submediterranean belt; widespread throughout the Alps.
