Ostiole conical, periphysate, with a flattened apex. Peridium 40-60 μm wide, composed of outer, polygonal, brown cells which deliquescence into fragments in KOH solution, and inner compressed, hyaline to pale brown cells, at the apex thickened, 78-112 μm wide, and composed vertically arranged cells. Asci cylindrical, 120-150 × 12-16 μm, stipitate, unitunicate, basal, 8-spored, blunt at apex, with a refractive, non-amyloid apical ring. Paraphyses in gel matrix, slender, septate, 3-4 μm wide, deliquescent.
