LICHALP

Acarospora melaplaca (Nyl.) Arnold

Syn.: Lecanora melaplaca Nyl.

Lichenised. Poorly known taxon.

Substrate: siliceous 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: a species with blackish-brown thallus and effigurate, very thin areolae, whose ecology and distribution need further study.
