Lecanora fuscescens (Sommerf.) Nyl.

Syn.: Biatora fuscescens (Sommerf.) Fr., Biatorella fuscescens (Sommerf.) Boistel, Lecidea fuscescens Sommerf.

Lichenised.

Substrate: lignum, bark, plant debris

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 probably circumboreal-montane species found on twigs of shrubs, especially Rhododendron ferrugineum in the subalpine belt, sometimes on lignum.
