Syn.: Biatora peziza Mont., Secoliga peziza (Mont.) Arnold

Lichenised.

Substrate: calciferous soil,

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) 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 mainly arctic-alpine, circumpolar species found on slightly calciferous soil rich in humus, and on terricolous bryophytes near or above treeline; widespread throughout the Alps, but generally rare.
