  Thallus adnate, to 2–4 cm wide. Lobes imbricate, sublinear-elongate, irregularly branched, generally narrow, occasionally more robust, 0.5–3 mm wide; margins sinuous; cilia sparse, 0.1–0.3 mm long, black. Upper surface pale grey to grey-green, flat, shiny, emaculate, smooth or weakly foveolate at first, becoming rugulose, lacking soredia and isidia, usually with granular white pruina towards lobe apices; lobe margins shiny, black. Medulla white. Lower surface black; lobes with a narrow, brown, naked marginal zone; rhizines moderately dense to dense, simple, black. Apothecia common, sessile to subpedicellate, 2–4 mm wide; disc concave, smooth, shiny, rarely sparsely pruinose; thalline exciple smooth. Ascospores broadly ellipsoidal to subglobose, 9–13 × 7–9 µm. Pycnidia numerous. Conidia bacilliform to weakly fusiform, 7–8 × 1 µm. CHEMISTRY: cortex K+ yellow; medulla K-, C+ red, KC+ red, P-; containing atranorin, chloroatranorin, lecanoric acid (major) and rarely traces of orsellinic acid.
  A very common species on branches of trees and shrubs, rarely on rock. Occurs throughout cooler, higher rainfall areas of southern and eastern Australia (W.A., S.A., Qld, N.S.W., A.C.T., Vic. and Tas.); also on both islands of New Zealand.
