Stilbohypoxylon samuelsii J. D. Rogers & Y.-M. Ju, Mycol. Res. 101: 137. 1997.

Stromata perithecioid, spherical, gregarious, 0.7-1.2 mm diam, usually bearing a conical to acicular synnematal remnant 0.2-0.4 mm long; surface black, rugulose, sometimes overlain with ochraceous scales; interior black, with a small amount of white tissue below perithecium; texture hard.

Perithecia spherical, 0.5-1 mm diam.

Ostioles papillate, usually encircled with a vaguely flattened area 0.2-0.3 mm diam.

Asci 235-285 (-315) mm total length x 12-15.5 mm broad, the spore-bearing part 175-210 (-245) mm long, the stipe 55-80 mm long, with apical ring bluing in Melzer's iodine reagent, coffin-shaped, 8-13 mm high x 5.5-7 mm broad.

Ascospores dark brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, (27.5-) 30-36 (-40) x 8.5-11 (-13) mm, with straight germ slit nearly spore-length on more flattened side.
