= ? Hypoxylon stigmateum Cooke, Grevillea 7: 4. 1878.

Stromata applanate, 1.8-7 cm long x 0.5-4 cm broad x 0.6-1 mm thick; outer dehiscing layer dark brown, 0.4-0.8 mm thick; mature surface blackish to shiny black; carbonaceous immediately beneath surface and between perithecia; tissue beneath perithecia inconspicuous.

Perithecia obovoid to tubular, laterally flattened, 0.1-0.2 mm diam x 0.5-0.8 mm high, usually with several packed inside the same stromatal locule, 0.3-0.4 mm diam, and sharing a common ostiolar canal.

Ostioles higher than stromatal surface, with openings coarsely papillate.

Asci 160-185 mm total length x 9-12.5 mm broad, the spore-bearing parts 120-150 mm long, the stipes 20-35 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 2-3 mm high x 4-5 mm broad.

Ascospores brown to dark brown, unicellular, ellipsoid, nearly equilateral, with narrowly to broadly rounded ends, smooth, 15.5-21 x (6.5-) 7-10 mm, with straight germ slit spore-length.
