LICHALP

Polysporina cyclocarpa (Anzi) Vězda

Syn.: Acarospora cyclocarpa (Anzi) Jatta, Biatorella cyclocarpa (Anzi) Lindau, Lithographa cyclocarpa Anzi, Sarcogyne cyclocarpa (Anzi) J. Steiner

Lichenised.

Substrate: calciferous rocks, intermediate rocks (such as calciferous schists)

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 dolomite and calcareous schists, but especially on pure limestone, with optimum above treeline; closely related to P. urceolata.
