Lower surface dark brown to black, sometimes pale brown at apices, ± smooth, dull, moderately or sparsely rhizinate. Rhizines concolorous with lower surface, to 1 mm long. Apothecia common, sessile to very short-pedicellate, concave to irregular, margins entire to weakly crenate or lacerate. Ascospores ellipsoid, 7-10.5 × 4.5-6 µm. Pycnidia common. Conidia weakly bifusiform 5-7 × 1 µm. Chemistry: Cortex K-, HNO3+ dark blue-green; medulla K+ yellow-red, C-, KC+ red, Pd+ orange. Four unidentified compounds related to stictic and norstictic acid.
