  Thallus squamulose, effuse or circular, with radiating marginal squamules. Prothallus usually well developed, reddish brown. Squamules 0.3–1.0 mm wide, adnate or ascending, elongate, incised or deeply divided, plane to weakly convex; upper side pale to medium green, glabrous or pruinose in the inner part, distinctly pruinose towards the lobe ends; margin pale, pubescent; isidia absent. Lacinules common, growing from the tips of ascending squamules, mainly in the inner part of the thallus. Upper cortex of type 1–2, 30–70 μm thick. Apothecia rare, 1.0–1.5 mm wide, rounded, solitary to conglomerate, convex and immarginate even when immature, dark reddish brown, with an indistinct concolorous margin. Proper exciple brown in the inner part, dark reddish brown at the rim. Hymenium red-brown. Hypothecium pale to medium brown. Ascospores simple, narrowly fusiform, 6–15 × 2–3 μm. Pycnidia partly immersed, dark red-brown. Conidia bacilliform, 9–10 × c. 1 μm.
CHEMISTRY: Cortex K–, P–; medulla K–, P+ orange; occurs in three chemical races: 1, containing zeorin (major), argopsin (major), norargopsin (minor); 2, containing zeorin (major), pannarin (major), ±dechloropannarin (minor); and 3, containing zeorin (major), dechloropannarin (major), ±pannarin (minor or trace).
