Description: Thallus fruticose, grey-yellowish when dry, dark grey-green when moist, of flattened, strap-shaped, 3-8 cm long, 1-6 mm wide, ascending to prostrate laciniae attached by a basal holdfast, often forming extensive colonies. Laciniae wrinkled, often longitudinally lacerated or dissected, with numerous elongate, raised pseudocyphellae bearing isidia-like granules. Cortex 2-layered, the outer part paraplectenchymatous, the inner part cartilaginous; medulla compact. Apothecia very rare, lecanorine, mostly terminal, but sometimes marginal in large specimens, with a cup-shaped, greenish disc and a minutely verrucose margin. Epithecium pale brownish-olive; hymenium and hypothecium colourless; paraphyses thick-walled, richly branched in upper part. Asci 8-spored, clavate to cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass) never penetrating through the entire d-layer, the wall K/I-, but the thin outer gel K/I+ blue, Bacidia-type. Ascospores 1-septate, hyaline, broadly ellipsoid, 12-16 x 4-6 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC- or KC+ pale yellow (cortex only), P-. UV-. Chemistry: cortex with usnic acid; medulla without lichen substances.

Note: on the top of isolated siliceous boulders manured by birds, e.g. in grasslands and pastures, common only wherever suitable substrata are present, especially in the mountains of Southern Italy (e.g. Sila Massif in Calabria, siliceous mountains of Sardinia).
