Lichenised. Poorly known taxon.
Substrate: calciferous rocks, 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: this rarely collected lichen of hard limestone and dolomite is worthy of further study.
