Lichenised.
Substrate:
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: on calciferous rocks in upland areas; closely related to V. muralis, but with larger spores, it has been reported only from the Eastern Alps (Austria, Italy) and the Carpathian Mts.
