Substrate: acidic soil (mostly on siliceous substrata)
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 with squamules closely attached to the soil, fusing to form a grey crust, perithecia with an entire involucrellum, and broadly ellipsoid to subglobose ascospores; on acidic soil, ecology otherwise poorly known; very rare and so far only reported from two localities in the Alps.
