Stromata applanate, 5-10 cm long x 2-5 cm broad x 1.5-2.5 mm thick; outer dehiscing layer dark brown, thin; mature surface black; carbonaceous immediately beneath surface and between perithecia; tissue beneath perithecia inconspicuous.

Perithecia tubular, 0.2-0.3 mm diam x 1.4-2.4 mm high.

Ostioles at the same level as or lower than stromatal surface, with openings punctate, usually surrounded by slightly raised rim, sometimes overlain with white substance.

Asci 190-220 mm total length x 13.5-14.5 mm broad, the spore-bearing parts 180-210 mm long, the stipes 10-15 mm long, with apical ring bluing in Melzer's iodine reagent, short-cylindrical, 6-7.5 mm high x 5.5-6 mm broad.

Ascospores dark brown to blackish brown, ellipsoid-inequilateral, with one end narrowly rounded and the other bearing a hyaline cellular appendage 1.5-2 mm long x 4-5.5 mm broad, smooth, 22-27 (not including appendage) x 11.5-13 mm, with straight, broad, faint germ slit spore-length on more convex side.
