Peridium 38-48 μm wide, composed of two regions, the outer of 4-6-layers of brown, thick-walled, polygonal cells which are melanized at the outermost layer, and the inner of 3-5-layers of thin-walled, hyaline, compressed cells. Asci 140-170 × 8-16 μm, ascospore-containing portion elliptic-saccate and 90-110 μm long, with a long stalk 50-70 μm long, arising basally and periphyerally in ascoma, 8-spored, unitunicate, with a non-amyloid, refractive apical ring. Paraphyses 3-4 μm wide, simple, deliquesce early. Ascospores 40-62 × 2.5-4 μm, cylindrical, overlapping 2-3-seriate to fasiculate in ascus, obtuse at apex, curved and rostrate at base, hyaline, aseptate or rarely becoming 3-septate, smooth, mucilaginous sheath sometimes present. | |||
