Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) 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 variable species which can produce both apothecia and soredia, found on siliceous boulders in humid and wind-protected situations, e.g. in deep gorges or along mountain creeks in woodlands, reaching beyond treeline in the Alps.
