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 nival belt (above the lower limit of perennial snow and glaciers)

Note: an ecologically wide-ranging, cool-temperate to arctic-alpine, circumpolar lichen found on wind-exposed boulders with a short snow-covering period, often on or near the top, with optimum above treeline. The species is highly polymorphic, with several infraspecific taxa; widespread throughout the siliceous Alps.
