Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, small, to 0.5 cm in diam., 0.15-0.2 mm thick, monophyllous, but many individual thalli growing together, giving the appearance of a polyphyllous thallus, with ascending and undulating margins and black, glossy, tumid edges, attached by a black, thick central holdfast. Upper surface mouse-grey, dull, rimose, paler toward the center. Lower surface dark brown to brown-black, smooth, but often scabrous around the umbilicus. Upper cortex palisade-plectenchymatous, 10-20 µm thick; algal layer continuous; medulla white, both loose and plectenchymatous, and compact and scleroplectenchymatous, 40-70 µm thick; lower cortex paraplectenchymatous, brown, ca 20 µm thick. Apothecia very rare, black, leiodisc. Photobiont chlorococcoid. Spot tests: medulla K-, C+ red, KC+ red, P-. Chemistry: medulla with gyrophoric acid.
