diagnosis
Diagnosis. Saprobic on dead bamboo culms, the surface of the host has a withered spot with a central protrusion. Sexual morph: Ascomata 386 – 658 × 129 – 237 μm (av. 487 × 169 μm, n = 10), scattered to gregarious, immersed with only ostiolar necks visible on the host surface or erumpent, globose to hemispherical with flattened base in section. Peridium composed of several layers of hyaline to dark brown cells of textura angularis. Hamathecium comprising dense, hyaline, branched and anastomosed, septate pseudoparaphyses. Asci 75 – 104 µm × 17 – 26 µm (av. 91 × 20 μm, n = 10), 8 - spored, cylindrical, fissitunicate, rounded at the apex with a shallow ocular chamber, small stalk at the base. Ascospores 25 – 27 × 5 – 7 μm (av. 26 × 6 μm, n = 10), biseriate, fusiform, hyaline, mostly straight, septum and constricted, smooth, guttulate, with a distinct gelatinous sheath. Asexual morph: undetermined.
