Description: Thallus foliose, heteromerous, dorsiventral, broad-lobed, appressed or slightly ascending at the periphery, forming large, up to 11(-15) cm wide, sometimes confluent, orbicular rosettes. Lobes rounded at tips, contiguous to imbricate, 2-5(-8) mm broad, mostly flat, brown, smooth to strongly rugose in central parts, with tiny, hyaline cortical hairs visible at least on some lobe-ends and on apothecial margins (stereo-microscope!). Lower surface dark brown to black, often paler at margins, with simple, black rhizines. Upper cortex paraplectenchymatous, with a pored epicortex, the cell walls containing isolichenan; medulla white; lower cortex paraplectenchymatous. Apothecia common, lecanorine, to 1.5(-2) cm across, sessile to shortly stipitate, with an initially strongly concave, then irregularly flattened, brown disc, and a reticulately ridged, often pseudocyphellate margin which nearly always has cortical hairs. Epithecium brown; hymenium and hypothecium colourless. Asci 8-spored, clavate, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid to broadly ovoid, 11-15 x 5.5-8(-10) µm. Pycnidia common, immersed. Conidia bacilliform, (6.5-)8-9 x 1 µm. Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC-, P-, N-; medulla K-, C+ red, KC+ red, P-. Chemistry: medulla with lecanoric acid.
Note: a mild-temperate lichen found on more or less isolated, mostly deciduous trees; optimum in the submediterranean belt, but common also in the beech belt of the southern mountains and of the western Alps; ecologically similar to Pleurosticta acetabulum.
