Outer excipular hyphae filamentous, interwoven, branched, with faint brown intracellular pigment, septate and without clamp connections.

Asci cylindrical, uniseriate, 8-spored, operculate, without significant reaction in Melzer's reagent (inamyloid).

Paraphyses filiform, slowly and progressively widening toward the apex, multiseptate, occasionally branched from the base, containing brown intracellular pigment.

Ascospores ellipsoidal, smooth, hyaline, thick-walled, often with polar guttular exudates.
