Anamorph: not known. Teleomorph: ascostromata perithecial, 0.6-1 mm diam., scattered, erumpent, with a well-developed neck that is sometimes cylindrical but more often laterally flattened to give an elliptical outline when viewed from above, or forming a crest up to 0.5 mm long. Interascal tissue of very narrow branched and anastomosed pseudoparaphyses. Asci 300-350 x 22-27 µm, cylindrical to narrowly cylindric-clavate, with a tapering stipe, thick-walled and fissitunicate with a small ocular chamber within the apical dome, not blueing in iodine, mostly 8-spored. Ascospores obliquely uniseriate to biseriately arranged, 50-80 x 12-20 µm, fusiform to fusiform-ellipsoidal, sometimes slightly curved, 7- to 11-septate with thick walls and ± lenticular lumina, slightly constricted at the ± median primary septum, dark brown but with one or both terminal cells almost hyaline, smooth or very minutely verrucose, apparently without a perispore, gelatinous sheath or appendages [the ornamentation may be derived from a degraded gelatinous sheath].
