Description: Thallus foliose, heteromerous, dorsiventral, narrow-lobed, closely adpressed, forming orbicular to confluent, to 11-14(-20) cm wide rosettes. Lobes elongate, contiguous to imbricate (0.5-)1-3(-5) mm wide, flat, the upper surface olive-brown to dark brown, usually paler in marginal parts, smooth to rugose in central parts, rarely pruinose on lobe ends, with laminal, distinctly pustular, 0.1-0.5 mm wide, hollow isidia which often proliferate, forming cauliflower-like cushions which easily abrade, resembling soralia. Lower surface olive-brown to brown, sometimes paler on lobe ends, with mostly simple rhizines. Upper cortex paraplectenchymatous, with a pored epicortex, the cell walls with Xanthoparmelia-type lichenan; medulla white; lower cortex paraplectenchymatous. Apothecia rare, lecanorine, to 10 mm across, with a brown disc and a margin which often bears pustular isidia. Epithecium brown; hymenium and hypothecium colourless; paraphyses simple; hypothecium colourless. 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-celled, hyaline, ellipsoid, 7-10 x 4-5 µm. Pycnidia rare, immersed. Conidia dumbbell-shaped, 5-6 x 1 µm Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC-, P-, N+ blue-green, UV-; medulla K-, C- or rarely C+ pink, KC+ orange-red, P-, UV+ white. Chemistry: medulla with glomelliferic and glomellic acids (both major), perlatolic acid (minor), rarely gyrophoric acid (minor).Note: a mainly temperate, common species of basic siliceous rocks, occurring also in urban areas (e.g. well into the outskirts of Rome), with a slightly suboceanic distribution in Europe.
Growth form: Foliose, broad lobed
Substrata: rocks
Photobiont: green algae other than Trentepohlia
