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: on slightly underhanging surfaces of siliceous rocks, especially crystalline schist, in humid and cold situations, with optimum in the alpine and nival belts, often starting the life-cycle on other crustose lichens; widespread in the Alps, but generally not common.
