LICHALP

Thelidium subrimulatum (Nyl.) Zschacke

Syn.: Verrucaria subrimulata Nyl.

Lichenised.

Substrate: calciferous rocks

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: this species, described from the Pyrenees, has been collected from very few localities in upland areas of Southern Europe, on limestone and calcareous schists; from the Alps there are only a few scattered records.
