Description: Thallus crustose, granular to verrucose-areolate, sometimes reduced to sparse granules near the apothecia, yellowish white to whitish grey, without a distinct prothallus. Medulla white, I- or I+ pale blue. Apothecia indistinctly lecanorine when young, later biatorine, sessile, 0.3-0.6(-0.8) mm across, with a pale to dark brown, sometimes grey-pruinose, convex disc and a thin, slightly prominent, smooth, entire, soon excluded thalline margin. Thalline exciple with very few algal cells, lacking crystals, ecorticate; proper exciple colourless, lacking crystals; epithecium brown to reddish brown, with pigment and crystals insoluble in K (the latter present only in apothecia with pale brown discs); hymenium colourless, 70-90 µm high, not inspersed with oil droplets; paraphyses capitate, the apical cells up to 3 µm wide; hypothecium colourless, 80-120 µm high, not inspersed. Asci 8-spored, clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, broadly ellipsoid to subglobose, (5-)7-11(-13) x 4-6(-7.5) µm, the wall <1 µm thick. Pycnidia frequent, immersed, black. Conidia thread-like, 7-11 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: thallus K+ pale yellow, C-, KC-, P+ orange-red. Chemistry: lobaric acid (major), fumarprotocetraric acid (major or absent), confumarprotocetraric acid (trace or absent), and unknowns (minor or absent).Note: a probably circumboreal-montane species found on twigs of shrubs, especially Rhododendron ferrugineum in the subalpine belt, sometimes on lignum; probably restricted to the Alps in Italy.
