  Thallus small-folioseor becoming subcrustose in centre, tightly adnate, to 1–4 cm wide, coalescing into larger patches. Lobes not or very weakly imbricate, flat to weakly convex, sublinear to irregular, 0.2–0.8 mm wide. Upper surface yellowish olive-brown to dark brown, dull throughout or slightly shiny at lobe apices, ±smooth becoming fissured and rugose to subareolate towards thallus centre, without isidia.

Apothecia common, sessile, to 2 mm wide; disc ±flat, dark brown; thalline exciple entire. Ascospores 8–10 × 4.5–6 µm. Pycnidia common. Conidia weakly bifusiform, 6–7 × 1 µm. CHEMISTRY: cortex K-, HNO3+ dark blue-green; medulla K+ yellow then orange or brownish orange, C-, P+ orange-red, UV-; containing fumarprotocetraric and protocetraric acids.
