Protoblastenia siebenhaariana (Körb.) J. Steiner var. siebenhaariana

Syn.: Biatora siebenhaariana Körb., Blastenia siebenhaariana (Körb.) Lettau, Protoblastenia rupestris (Scop.) J. Steiner subsp. siebenhaariana (Körb.) A.L. Sm.

Lichenised.

Substrate: intermediate rocks (such as calciferous schists), 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: a mainly arctic-alpine, probably circumpolar lichen found on base-rich or calciferous siliceous rocks and on dolomite in upland areas; not frequent in the Alps, but widespread, and locally common.
