Stromata peltate, with convex top and constricted base, usually coalescent, with conspicuous perithecial mounds, 0.5-4 cm diam x 1.5-7 mm thick; surface dark brown to blackish brown; blackish granules immediately beneath surface, with KOH-extractable pigments sienna (8), apricot (42), olivaceous (48) or greenish olivaceous (90); the tissue below the perithecial layer conspicuous, blackish.

Perithecia obovoid, 0.4-0.7 mm diam x 0.5-0.7 mm high.

Ostioles conical-papillate.

Asci 150-170 mm total length x 4.5-6 mm broad, the spore-bearing parts 70-82 mm long, the stipes 75-100 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 1 mm high x 2 mm broad.

Ascospores light brown to brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 8.5-12 x 3.5-5 mm, with straight germ slit less than spore-length; perispore dehiscent in 10% KOH, smooth; epispore smooth.
