Stromata raised-discoid, with concave surface, 1-2.2 cm diam x 2.5-3 mm thick, with dark brown, distinct raised margins originating from outer dehiscing layer; mature surface black; dark brown, woody immediately beneath surface and between perithecia, with carbonaceous tissue encasing each individual ostiole; tissue beneath perithecia 1 mm thick, composed of white, coriaceous fungal tissue and embedded carbonaceous fragments; tissue of margins and bottoms 0.3-0.4 mm thick, dark brown, woody, with embedded carbonaceous fragments.

Perithecia tubular, 0.3-0.4 mm diam x 0.7-1.5 mm high.

Ostioles at the same level as or lower than stromatal surface, with openings punctate, sometimes overlain with white substance.

Asci 120-155 mm total length x 7-8 mm broad, the spore-bearing parts 95-125 mm long, the stipes 25-35 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 1 mm high x 2.5-3 mm broad.
