Syn.: Staurothele solvens (Anzi) Zschacke var. fusca Asta, Clauzade & Cl. Roux [invalidly published, ICN Art. 40.1 + 8]

Lichenised.

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: differing from the type variety in the dark brown thallus and the 8-spored asci; on periodically inundated, compact calcareous rocks at mid- to moderately high elevations; so far only known from the Western Alps (France).
