  Thallus foliose, loosely to tightly adnate, to 2–12 cm wide. Lobes discrete to imbricate or entangled, flat, sublinear to linear-elongate, 1–3 (–5) mm wide, lacking laciniae. Upper surface yellowish brown, reddish brown to dark brown, dull to shiny at lobe apices, smooth to weakly rugose at thallus margins, becoming rugulose on older lobes, without isidia. Lower surface dark brown to black, often paler at lobe apices; rhizines moderately dense to dense, simple, to 1.5 mm long, black. Apothecia common, sessile or shortly pedicellate, to 11 mm wide; disc concave to flat or rarely somewhat convex, red-brown to dark brown; thalline exciple prominent, entire, crenulate or incised. Ascospores 9–11 × 5–6 µm. Pycnidia common. Conidia bifusiform or occasionally weakly fusiform, 4.5–7 × 1 µm. CHEMISTRY: cortex K-, HNO3+ pale to dark blue-green; medulla K-, C-, KC-, P-, UV-; containing stenosporic acid or divaricatic acid, with accessory perlatolic acid. Also reported to contain accessory gyrophoric acid (C+ rose, KC+ rose) and unidentified compounds (see T.L.Esslinger (op. cit. 136, 1977) for a full discussion on the variability of the chemistry in this species), but these have not been observed in Australian specimens.
  A very common and variable species (W.A., S.A., Qld, N.S.W., Lord Howe Is., A.C.T. and Vic.) and as presently understood may well incorporate more than one taxon. Also occurs in Europe, northern and southern Africa and New Zealand. Grows on rock or on soil.
