Protoblastenia terricola (Anzi) Lynge

Syn.: Biatora rupestris (Scop.) Fr. var. terricola Anzi, Biatora terricola (Anzi) Th. Fr., Blastenia terricola (Anzi) Lindau, Lecidea terricola (Anzi) Th. Fr., Protoblastenia siebenhaariana (Körb.) J. Steiner var. terricola (Anzi) Hafellner & Türk
Lichenised. Poorly known taxon.
Substrate: calciferous soil
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 soil over weakly calcareous or dolomitic substrata in upland areas; perhaps this is only a terricolous morph of P. siebenhaariana; most frequent in the southern part of its distributional range.
