Description: Thallus fruticose, yellowish green to greenish grey, shrubby, forming small pillows 1-3 cm in diam. Laciniae simple or branched only at base, crowded, erect, flattened and strap-shaped, 0.5-1(-3) mm wide and 0.5-1(-3) cm long, foveolate-reticulate, sometimes with a few pseudocyphellae, the apices more or less broadened. Medulla white, solid. Apothecia absent to numerous, lecanorine, mostly subapical, concolorous with thallus, with a concave disc and a rugose thalline margin. 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, slightly curved, 9-16 x 4-6 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC- or KC+ yellowish, P-. Chemistry: cortex with usnic acid.
