Perithecia globose, blackish, deeply sunken in the substrate, opening to the exterior via an aperture (ostiole).

Asci cylindrical to clavate, with a long pedicel, polyspored (according to literature up to 64 spores per ascus), these spores tightly packed inside the ascus and difficult to observe.

Paraphyses forming a very dense mass between the asci, filiform, hyaline, septate and protruding above the level of the asci.

Ascospores allantoid (sausage-shaped), smooth, thin-walled, with yellowish to pale brown pigment inside.
