Description: Thallus foliose, heteromerous, dorsiventral, tightly adnate, forming up to 2(-3) cm wide rosettes, yellow to yellowish grey in shade-forms, esorediate. Lobes flat to convex, very short, 0.2-0.7(-1) mm wide, broadening towards apices which are finely divided into 0.1-0.3 mm wide, rounded lobe-tips; lower surface white, somewhat wrinkled, with scattered short, white hapters. Apothecia lecanorine, extremely abundant, usually crowded and occupying most of the rosette obcuring the thallus, circular or deformed by mutual compression, laminal, substipitate, to 4 mm across (usually less), with a yellow-orange, concave to flat disc and a yellow to grey-yellow, thin, smooth to crenulate, finally sometimes excluded thalline margin. Thalline exciple paraplectenchymatous; epithecium orange-brown, c. 10 µm high, K+ purple-red; hymenium colourless, 40-90 µm high; paraphyses simple or sparingly branched, the apical cells swollen; hypothecium colourless to pale brown, 15-50 µm high. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 11-15 x 5-8 µm, the equatorial thickening (“septum”) 2-4(-6.5) µm. Pycnidia common, immersed, slightly darker orange than upper surface. Conidia ellipsoid, 2-3 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ purple-red, C-, KC-, P-, UV+ intensely orange-red. Chemistry: parietin (major), fallacinal, emodin, teloschistin and parietinic acid corresponfing to chemosyndrome A of Søchting (1997). Note: a mainly boreal-montane, circumpolar species found on isolated trees and sun-exposed branches and small twigs, on wooden poles and fences; most frequent in the Central Alps, rarer in the eastern Apennines, extending southwards to Calabria and the mountains of Sicily, where it is very rare.
