Description: Thallus foliose, heteromerous, dorsiventral, narrow-lobed, closely adpressed, forming orbicular, up to 4(-6) cm wide rosettes. Lobes 0.5-1.5(-2) mm broad, flat to usually convex, whitish grey to (rarely) cream-coloured, emaculate and epruinose. Lower surface white to brownish, with simple rhizines. Upper cortex paraplectenchymatous; medulla white; lower cortex prosoplectenchymatous, with the lowermost part gradually forming rounded, isodiametric cells. Apothecia common, lecanorine, to 3(-4) mm diam. with a sometimes white-pruinose, otherwise black disc and a smooth thalline margin. Epithecium brown; hymenium and hypothecium colourless; paraphyses slender, simple or forked in upper part, the apical cells clavate, with a thin, dark brown cap. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, brown, ellipsoid, (13-)15-22(-28) x (6.5-)7-11(-12) µm, the wall thickened at apex and at septum, Physcia-type. Pycnidia common, immersed, black. Conidia subcylindrical, 4-6 x 1 µm. Photobiont chlorococcoid. Spot tests: upper cortex K+ yellow, C-, KC-, P- or P+ faintly yellow; medulla K-, C-, KC-, P-. Chemistry: upper cortex with atranorin. Note: a (cool-) temperate to southern boreal-montane, circumpolar lichen of isolated trees. P. biziana, P. aipolia and P. stellaris, although often overlapping in their altitudinal distributions, are altitudinal vicariants in Italy, P. stellaris has the optimum in and above the beech-belt, from Sicily to the Alps where it is most common, and is the most ‘continental’ of the three species.
