| Thallus foliose, unattached or loosely adnate, forming rosettes to 4–6 cm wide. Lobes loosely imbricate, sublinear, subirregularly to subdichotomously branched, narrow at apices (0.7–1.5 mm), wider at base (to 6 mm); lobules in thallus centre, extensively branched, ascending, subterete to cylindrical, 0.2–0.4 mm wide, sometimes tipped with black at apices. Upper surface yellow to yellow-green, convex, glossy or dull, emaculate, smooth becoming rugulose, lacking soredia and isidia; lobe margins often black. Medulla white. Lower surface ±canaliculate, shiny, rugose, shallowly faveolate, pale brown to tan; rhizines sparse to moderately dense, simple, tufted or branched, ±dichotomously or palmately branched, brown to black. Apothecia not seen in Australian material. Pycnidia rare. Conidia bifusiform, 5–7 × 0.5 µm. CHEMISTRY: cortex K-, UV-; medulla K+ yellow then orange, C-, P+ orange; containing usnic acid, stictic acid (major), constictic acid, norstictic acid (minor), cryptostictic acid (trace) and with or without associated unidentified compound (trace). | ||
| Scattered on arid soils in mallee areas of southern Australia (W.A., S.A., Vic. and Tas.); also on the South Is. of New Zealand and in South Africa. | ||
