  Thallus forming rosettes to 1–4 cm wide when wet, these contracting into convex clumps to 0.5–1 cm wide, rolling up and becoming subglobose with underside of lobes outermost when dry. Lobes separate, not at all imbricate, linear-elongate, 1–3 mm wide; apices rounded, curling inwards when dry. Upper surface pale yellow to pale yellow-green, becoming pale olive-green, often shiny, sparsely maculate, lacking soredia. Lower surface rarely partly canaliculate, rugulose. Apothecia rare, sessile to subpedicellate, 0.5–2.5 mm wide; thalline exciple smooth, thick, prominent, crenulate or minutely fissured, concolorous with thallus. Ascospores 8–10 × 4–5 µm. Pycnidia rare. Conidia bifusiform, 5–7 × 1 µm. CHEMISTRY: cortex K-, UV-; medulla K+ pale brown, C-, P+ orange-red; containing usnic acid, fumarprotocetraric acid, succinprotocetraric acid and ±protocetraric acid (trace).
  Widespread in W.A. and S.A., rather rare in Qld, widespread in N.S.W., A.C.T. and Vic. An early report of this species from Tas. is almost certainly the result of a locality error. Also occurs on the South Is. of New Zealand.
