Thallus foliose, adnate, to 4–9 cm wide. Lobes contiguous centrally, separate at periphery, not imbricate, linear-elongate, subdichotomously branched, 0.8–3 mm wide, without lobules; cilia dense, conspicuous, to 2.5 mm long, black. Upper surface yellow-green, flat to weakly convex, shiny at lobe apices, smooth, cracked on older lobes, maculate, without isidia. Lower surface brown to dark brown; rhizines moderately dense, simple or occasionally dichotomously branched, coarse, brown to black. Apothecia common, to 6 mm wide; disc ±flat or shallowly concave, cinnamon-brown; thalline exciple ecoronate, retrorsely rhizinate. Ascospores ellipsoidal, 7–10 × 4–6 µm. Pycnidia common, flat to slightly emergent, punctiform, to 0.1 mm wide. Conidia bifusiform, 6–8 × 1 µm. CHEMISTRY: cortex K-, UV-; medulla K+ yellow, C-, P+ orange; containing usnic acid, norstictic acid (trace), stictic acid (major), constictic acid (minor), cryptostictic acid (trace), ±menegazziaic acid (trace), ±hypostictic acid (trace) and ±atranorin. | ||
This common, endemic species occurs from north Qld through N.S.W. to East Gippsland (Vic.), the Bass Strait Islands and northern and eastern Tas. Common on rock in temperate, open forests in coastal and hinterland areas; in tropical and subtropical areas this species is much more common on trunks and canopy branches of rainforest trees. | ||
