Thallus endoperidermal to epiperidermal, thin, effuse; surface whitish or greenish gray, in older specimens pale tan, smooth, occasionally with reddish or orange pigment crystals and areas of pinkish staining; prothallus brown, often as contact lines. Photobiont trentepohlioid alga, endoperidermal; cells (7.8–) 11.7 (–18.2) × (5.2–) 8.3 (–15.6) µm (n = 39), in short branched chains. Ascomata dispersed, sessile, elongate to furcate, lirellate with ±straight branches and acute tips, (0.4–) 1.0 (–1.6) × (0.2–) 0.3 (–0.5) mm (n = 60); disk flat, brown, often covered with whitish pruina; margin thick, coated with red or orange pruina.
