| Thallus foliose, loosely to moderately adnate, to 7–10 cm wide. Lobes variable, often forming a dense, imbricate mat, ±flat, subirregular to linear-elongate; primary and marginal lobes subdichotomously branched, 2–4 (–8) mm wide, with subrotund apices; laciniae sometimes developing from thallus centre, elongated, dichotomously branched, 0.5–1.5 mm wide; without lobules. Upper surface yellow-green, darkening with age, shiny, emaculate, smooth to slightly rugulose, becoming ±rugose and developing transverse cracks in older lobes, lacking soredia and isidia. Medulla white. Lower surface rugose, papillate, often shiny, pale brown to brown, darker in centre; rhizines moderately dense, especially near lobe margins, simple, often tufted, rarely dichotomously branched, slender, concolorous. Apothecia occasional, sessile, 3–6 mm wide; disc concave, becoming flat, red-brown; thalline exciple rugulose, entire, thick and involute, becoming crenulate. Ascospores 8–10 × 6 µm. Pycnidia common. Conidia bifusiform, 5–7 × 0.5 µm. CHEMISTRY: cortex K-, UV-; medulla K+ yellow then dark red, C-, KC+ red, P+ orange; containing usnic acid, salazinic acid and consalazinic acid. | ||
| Common, found on soil and spreading onto rock in drier mountain and subarid lowland areas of southern Australia (W.A., S.A., Qld, N.S.W., A.C.T., Vic. and Tas.); also on the South Is. of New Zealand and in South America (Argentina). | ||
