Syn.: Staurothele sapaudica Asta, Clauzade & Cl. Roux [invalidly published, ICN Art. 40.1 + 8]

Lichenised.

Substrate:

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) 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 species resembling S. ventosa, but thallus brown and continuous, ascomata with poorly developed involucrellum, hymenial algae narrowly oblong, and ascospores persistently pale; together with S. solvens on periodically moist calcareous rocks, e.g. along streams at high elevations; only known from the Alps, with certainty only from the Western Alps (France).
