Ostioles lower than the stromatal surface.
Asci 100-130 mm total length x 5-6.5 mm broad, the spore-bearing parts 50-65 mm long, the stipes 50-68 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 0.2-0.5 mm high x 1-1.5 mm broad.
Ascospores brown to dark brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 8-9.5 (-11) x 4-5 mm, with straight or slightly sigmoid germ slit spore-length; perispore dehiscent in 10% KOH, with inconspicuous coil-like ornamentation; epispore smooth.
