Substrate: living mosses, acidic soil (mostly on siliceous substrata)
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 of unclear relationship, perhaps belonging to Sporodictyon, with a whitish granulose thallus, and ellipsoid, muriform (to c. 60 µm long) ascospores which are first hyaline, then brownish; on cushions of mosses over siliceous substrata; rare, from the boreal-alpine to the temperate-alpine zone, with a few records from the Eastern Alps (Austria).
