| Thallus foliose, adnate, to 5 cm wide. Lobes contiguous centrally, separate at periphery, not imbricate, linear-elongate, subdichotomously branched, 1.5–3 mm wide, lacking lobules; cilia dense, conspicuous, to 2 mm long, black. Upper surface yellow-green to yellow-brown after storage, flat to weakly convex, shiny at lobe apices, smooth, weakly maculate, lacking isidia. Lower surface brown to dark brown; rhizines dense, simple or occasionally sparingly dichotomously branched, brown to black. Apothecia common, to 3 mm wide; disc ±flat or shallowly concave, cinnamon-brown; thalline exciple ecoronate, retrorsely rhizinate. Ascospores ellipsoidal, 7–9 × 4–6 µm. Pycnidia common, flat to slightly emergent, punctiform, to 0.05 mm wide. Conidia bifusiform, 6–8 × 1 µm. CHEMISTRY: cortex K-, UV-; medulla K+ yellow then dark red, C-, P+ orange; containing usnic acid, norstictic acid (major), connorstictic acid (minor) and hyposalazinic acid (trace). | ||
