Asci clavate, 8-spored, with spore arrangement between biseriate and irregular in the upper part of the ascus, with an amyloid apical thickening.

Paraphyses filiform, smooth, hyaline, heavily septate, mostly simple or in rare cases bifurcate in the terminal cells, with a distinct swelling in the terminal cell and surface pigments staining violaceous in KOH.

Ascospores cylindric-ellipsoidal, smooth, hyaline, thin-walled, in some cases with a slight median constriction, and containing vacuolar internal content.
