LICHALP

Ainoa geochroa (Körb.) Lumbsch & I. Schmitt

Syn.: Biatora geochroa Körb., Lecidea geochroa (Körb.) Lettau, Trapelia geochroa (Körb.) Hertel

Lichenised.

Substrate: acidic soil (mostly on siliceous substrata)

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: on fresh acidic mineral soil in open vegetation developing in areas with a long snow cover (Solorinion croceae-communities); distribution in the Alps poorly known, perhaps overlooked.
