Syn.: Lecanora subradiosa Nyl. var. caulescens J. Steiner
Lichenised.
Substrate: siliceous rocks
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 lichen forming minute, podetia-like structures growing in dense cushions of c. 1-2 cm in diam. and up to 1 cm high, otherwise like subsp. swartzii; under overhangs of siliceous rocks, from the montane to the lower alpine belt; the distribution is poorly known, and in the study area is so far limited to the Eastern Alps (Austria).
