LICHALP

Caloplaca arnoldiiconfusa Gaya & Nav.-Ros.

Syn.: Calogaya arnoldiiconfusa (Gaya & Nav.-Ros.) Arup, Frödén & Søchting

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: in the past this species, which is widespread in Central Europe, was confused with C. arnoldii, which substitutes in upland areas, on vertical, sun-exposed calcareous and dolomitic rocks.
