Cetrariella commixta (Nyl.) A. Thell & Kärnefelt

Syn.: Cetraria commixta (Nyl.) Th. Fr., Melanelia commixta (Nyl.) A. Thell, Parmelia commixta (Nyl.) Th. Fr., Platysma commixtum Nyl.

Lichenised.

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 nival belt (above the lower limit of perennial snow and glaciers)

Note: a circumpolar, arctic-alpine lichen found on hard siliceous rocks wetted by rain in upland areas; somehow more bound to cold-humid sites than the superficially similar Melanelia hepatizon; widespread in the Alps.
