Saprobic on grass stems. Sexual morph: Ascomata 130 – 180 μm high, 250 – 350 μm diam., scattered, immersed, subepidermal, smooth, brown mycelium ramifying in the host tissue, broadly ellipsoidal to globose, smooth-walled. Ostiole papillate, 15 – 30 μm long, 20 – 25 μm wide, central, terete, flush to papillate, intraepidermal, of 2 – 6 layers of brown polygonal 4 – 7 × 3 – 6 μm cells around 10 – 50 μm diam., ostiole without periphyses. Peridium surface composed of cells of textura angularis, lateral layers uniform, 12 – 18 μm thick, composed of brown, 3 – 6 layers of textura prismatica, 6 – 11 × 3 – 5 μm pseudoparenchymatous cells, thicker above the smaller darker cells. Hamathecium composed of numerous, 1 – 3 μm broad, paraphyses with thin septa at 10 – to 30 μm intervals without guttules and with thin copious slime coating. Asci 60 – 110 × 12 – 20 μm, 8 – spored, bitunicate, fissitunicate, numerous, cylindrical and short pedicellate. Ascospores 23 – 28 × 8 – 10 μm (L/W 3), overlapping biseriate, yellowish brown, narrowly fusiform, enlarged at the third cell from the apex, 5-septate, straight or slightly curved, slightly constricted at the first septum which is sub-median, not constricted at the other septa, smooth-walled, without guttules and with a prominent sharply delimited 2 – 8 μm mucilaginous sheath (description from Shoemaker and Babcock 1989). Asexual morph: Undetermined.
