Syn.: ?Verrucaria cincta Hepp non Fée

Lichenised. Poorly known taxon.

Substrate: calciferous 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 calcicolous species of the V. muralis-group, with a very thin, whitish thallus, ascomata (to 0.3 mm in diam.), a dimidiate involucrellum, and ellipsoid to oblong ascospores (to c. 20 µm long); rare throughout Central Europe, with a few scattered records from the Alps.
