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 very poorly known species reported from several scattered localities in eastern Central Europe. The Italian material, collected on granite near Bormio, was distributed by Anzi (Lich. Lang. 570).
