| Thallus foliose, adnate, thick, to 4–5 (–7) cm wide. Lobes sometimes imbricate, flat, subirregular to sublinear-elongate, irregularly branched, 1–2 (–3) mm wide; sometimes developing laciniae towards thallus centre, 0.5–1 mm wide. Upper surface pale yellow to yellowish green, dull, sometimes shiny towards apices, emaculate, slightly rugulose, lacking soredia; lobes often black-margined towards apices; isidia dense, cylindrical, extensively branched, coralloid or ±flattened, epicorticate and ultimately inflated at apices, becoming erumpent, robust (0.2 mm wide), to 2 mm high. Medulla white. Lower surface pale brown, darker towards lobe apices; rhizines sparse to moderately dense, simple, concolorous. Only immature apothecia observed: subpedicellate, to 1 mm wide; thalline exciple thick, isidiate, involute. Pycnidia not seen. CHEMISTRY: cortex K-, UV-; medulla K-, C-, KC+ rose, P-; containing usnic acid, norlobaridone, constipatic acid, protoconstipatic acid, ±loxodin, ±scabrosin 4-acetate 4'-butyrate, ±scabrosin 4-acetate 4'-hexanoate, ±scabrosin 4,4'-dibutyrate and ±scabrosin 4,4'-diacetate (trace). |  |

| Rather rare, endemic, in arid, inland W.A., S.A., N.T., Qld and N.S.W. Grows on soil, rarely spreads onto rock. | ||
