Lecanora boligera (Norman ex Th. Fr.) Hedl.

Syn.: Biatora nylanderi auct. non Anzi, Lecidea fuscescens Sommerf. f. boligera Norman ex Th. Fr.

Lichenised.

Substrate: bark

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) 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 circumboreal-montane species found on twigs of Rhododendron and other shrubs in open, often windy situations, especially on small branches, sometimes on plant debris and lignum, with optimum near treeline.
