Syn.: Polyblastia guestphalica J. Lahm ex Körb., Porphyriospora guestphalica (J. Lahm ex Körb.) Arnold, Staurothele orbicularis auct. non (A. Massal.) Th. Fr.; incl. Staurothele dalmatica Servít

Lichenised. Poorly known taxon.

Substrate: calciferous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) 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 calcareous walls and boulders, and on large pebbles in dry grasslands; related to S. orbicularis, and in need of further study.
