Staurothele areolata (Ach.) Lettau

Syn.: Pyrenula areolata Ach., Staurothele clopima auct. non (Wahlenb.) Th. Fr., ?Staurothele turgidella Vain.

Lichenised.

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: an arctic-alpine to boreal-montane, circumpolar species found on calcareous to basic siliceous rocks wetted by rain in open habitats (e.g. on boulders in alpine and subalpine grasslands); very common throughout the Alps.
