LICHALP

Psoroglaena biatorella (Arnold) Lücking & Sérus.

Syn.: Leucocarpia biatorella (Arnold) Vězda, Microglaena biatorella Arnold

Lichenised.

Substrate: living mosses, plant debris, 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: an inconspicuous lichen found on thin layers of more or less calciferous, humus-rich ground, or over epilithic mosses, mostly in upland areas; probably overlooked and more widespread, but never common in the Alps.
