Asci cylindrical, eight-spored, operculate, 250 to 300 µm long, 18 to 24 µm wide, with uniseriate spore arrangement within the ascus, basal croziers, and inamyloid in Melzer's reagent.

Paraphyses filiform, septate, 2.5 to 3.5 µm wide, with apical enlargements of 9 to 12 µm, with orange intracellular pigment, projecting slightly above the asci.
