Anamorph: not known Teleomorph: ascostromata hysterothecia with an inconspicuous longitudinal slit, (230-) 300-350 µm long, 100-130 µm wide, (250-) 450-600 µm high, elliptical (sometimes narrowly so) from above, widening upward from a narrow base to a longitudinal ridge when viewed from the side and ± ovate in vertical transverse section, black, smooth, sometimes concentrically striate, superficial, scattered, in no particular alignment. Peridium with side walls thin, brittle, at the base composed of fused interwoven red-brown epidermoidal cells, composed of parallel hyphal tissue above, at the slit margin perpendicular and markedly elongate-parallel, with a layer of interwoven hyaline thin-walled hyphae forming the floor of the cavity. Interascal tissue composed of filiform pseudoparaphyses 1-1.5 µm diam. with rounded ends, hyaline, smooth, sparsely septate, branched and anastomosed, exceeding the asci and plugging the slit when dry. Asci 170-210 x (6-)8-10 µm, cylindrical, tapering to a lobed base, fissitunicate, the apex rounded, I-, 8-spored, arising from croziers and in parallel from the cavity floor. Ascospores 240-270(-280) x 1.5-2 µm (one and a half times the length of the asci), many-septate, septa 10-12 µm apart, becoming helically arranged within the ascus at maturity, filiform, very long, yellowish to pale brown, smooth, not constricted at the septa, without a gelatinous sheath or appendages.
