  Thallus adnate, to 5–15 cm wide. Lobes elongate, irregular, 2–8 mm wide, without lobules; margins crenulate, sinuous, sometimes pruinose, darkening. Upper surface pale greenish grey to grey or grey-black, flat to convex, smooth to conspicuously rugose-plicate in older lobes, faveolate or not, waxy, matt to slightly shiny, without soredia and isidia; pseudocyphellae punctiform, developing along lobe margins and on thalline exciple of apothecia. Lower surface smooth or rugose-papillate, shiny, pale buff or creamish; rhizines sparse to moderately dense, simple, concolorous. Apothecia common, crowded centrally, subpedicellate, 2–6 mm wide; disc imperforate, concave to ±flat; thalline exciple thin, crenate, persistent, rugose, striate-verrucose, pale flesh-coloured or concolorous with thallus. Ascospores broadly ellipsoidal, 10–16 × 6–10 µm. Pycnidia common; ostiole grey-black, ±pruinose. Conidia filiform, 7–9 × 0.8–1 µm. CHEMISTRY: cortex K+ yellow; medulla K-, C+ red, KC+ red, P-; containing lecanoric acid (major), ±atranorin and ±chloroatranorin.
  Very common in drier areas of southern and eastern Australia (W.A., S.A., Qld, N.S.W., A.C.T. and Vic.; also occurs in New Zealand. Grows on bark or wood.
