Margin,in cross section 40 µm thick at the broadest point, nearly obsolete below, the wall consisting of 4-5 layers of interwoven brown hyphae 1.5 µm diam., the crystalline layer moderately prominent, the periphysoids 5 x l5 µm, unbranched, sparse. Subhymenium 5-10 µm thick, J-, of small angular cells resting on a continuation of the brown wall. Paraphyses numerous, filiform, 1.0 µm thick below, enlarged to 1.5-2.0 µm above, faintly brown, J-. Asci 400-475 x 5-6 µm, the cap 6-7 µm thick, pierced by a narrow pore. Ascospores nearly as long as the asci, strictly filiform, 2.0 µm broad, septate, the cells 2.5-4 µm long.
