Thallus slate gray to grayish black, olive when wet, foliose, adnate to ±loose, papery thin; outline ± orbicular; lobes distinct, elongate, ± broadened and flattened, regularly spreading (fan-shaped), composed of two layers owing to the adherence of thin lobes folded upon one another; surface smooth to barely striate, typically spotted with small pits where the two layers of thallus lobes are riveted to one another; lacking isidia; apothecia common, sessile to shortly stalked, laminal; disk pale to deep reddish brown, initially barely concave, soon flattened; margin lecanorine, often pale brownish, rarely concolorous with thallus, with a broad paraplectenchymatous thalline exciple and an indistinct, thin, prosoplectenchymatous proper exciple; ascospores ellipsoid to subfusiform, ends often pointed, muriform, 4-5 transversely, and 1-2(-3) longitudinally septate, 25-39 x 10-14 µm.
