Substrate: intermediate rocks (such as calciferous schists)
Altitudinal distribution: 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 growing on calciferous schists which perhaps belongs to Toninia, with ascomata as in the “Catillaria athallina-group” and mainly non-septate ascospores; rare, in the Alps so far known from a single locality only.
