| Thallus adnate, coriaceous, to 5–6 cm wide. Lobes imbricate, subirregular, 5–20 mm wide; margins crenate or irregularly incised; cilia simple or branched, 0.5–3 mm long. Upper surface pale grey to grey-green, flat, emaculate, smooth or becoming rugose; cortex fragile; isidia laminal and marginal, short-cylindrical, becoming coralloid, granular or occasionally dissolving into soredia, often ciliate at apices. Medulla white. Lower surface black, with a brown, erhizinate marginal zone; rhizines dense, simple, slender, to 1 mm long. Apothecia rare, submarginal, pedicellate, 3–8 mm wide; disc imperforate; thalline exciple rugose, isidiate. Ascospores 25–35 × 12–18 µm wide. Pycnidia rare. Conidia sublageniform, 3–4 × 1 µm. CHEMISTRY: cortex K+ yellow; medulla K+ yellow, C-, P+ orange, UV-; containing atranorin, chloroatranorin, stictic acid (major), constictic acid (minor), cryptostictic acid (trace), norstictic acid (trace), ±menegazziaic acid (trace) and ±connorstictic acid (trace). | ||
| A cosmopolitan species, widespread in humid habitats in temperate and tropical regions, common in coastal areas of eastern Australia (Qld, N.S.W., Vic. and Tas., also Lord Howe Island, Norfolk Island). Grows on bark and rock. | ||
