| in J.A.Elix, J.Johnston & P.M.Armstrong, Bull. Brit. Mus. (Nat. Hist.), Bot. 15: 339 (1986). T: near Diggers Creek, Kosciusko National Park, N.S.W., 21 Jan. 1976, J.A.Elix 1718; holo: CANB; iso: MEL. | ||
| TThallus foliose, loosely to moderately adnate, to 4–7 cm wide. Lobes contiguous to imbricate, flat, linear-elongate, dichotomously to subirregularly branched, generally irregularly constricted, 0.3–1 (–1.5) mm wide; laciniae often densely imbricate, resulting in a compact mat. Upper surface yellow-green, darkening with age, shiny becoming dull, emaculate, smooth, lacking soredia and isidia; lobes with conspicuous black margins. Medulla white. Lower surface shiny, black; rhizines moderately dense, ±projecting beyond margins, often rhizinate to margins and appearing ciliate, simple or rarely dichotomously branched, to 2 mm long, black. Apothecia rare, sessile, 0.5–1.5 mm wide; disc concave, dark brown; thalline exciple smooth. Ascospores 6–9.5 × 3.5–5.5 µm. Pycnidia common. Conidia bacilliform, 6–7 × 0.5 µm. CHEMISTRY: cortex K-, UV-; medulla K+ yellow, C-, P+ orange; containing usnic acid, stictic acid (major), constictic acid and small quantities of norstictic acid and cryptostictic acid. | ||
| Relatively common, on rock in cooler mountain and subalpine areas of southern Australia (W.A., S.A., N.S.W., A.C.T., Vic. and Tas.); also on the South Is. of New Zealand and in South Africa. | ||
