Asci 195-250 mm total length x 8-10 mm broad, the spore-bearing part 80-90 mm long, the stipe 110-160 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 1 mm high x 3.5-4 mm broad.

Ascospores brown to dark brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 12.5-15.5 x 6-7.5 mm, with straight germ slit spore-length on convex side; perispore dehiscent in 10% KOH, smooth; epispore smooth.
