Lichenised.

Substrate: siliceous rocks, intermediate rocks (such as calciferous schists)

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 cool-temperate to arctic-alpine, circumpolar lichen found on boulders of base-rich to weakly calciferous siliceous rocks, usually on steeply inclined surfaces, often (but not always) parasitic on other crustose lichens, with optimum near or above treeline; widespread throughout the Alps.
