| Description： |
Mycelia superficial with abundant erect conidiophores. Ascostomata scattered, superficial, dark brown, subglobose, flattened at the apex, ostiolate, setose, 90-190 μm high, 100-215 μm wide. Setae rigid, dark brown, smooth, simple, thick-walled, septate, 130-165 μm long, 7-10 μm wide at the base. Peridium 7-15 μm thick is composed of 4-8 layers of dark brown to brown, compressed pseudoparenchymatous cells. Paraphyses (sensu Eriksson, 1981) filiform, colourless, septate; periphyses in ostiole. Asci unitunicate, 8-spored, deliquescing early, 80-110 × 11-14 μm, without any apical structures. Ascospores distichhous in the ascus, narrowly ellipsoid, mostly curved, 0-1-septate, somewhat constricted at the septum, mostly 4 guttulate, colourless, smooth, appearing finely verruculose under oil immersion, 16-27.5 × 4-8 μm. | |||

| Note： |
The relatively longer ascospores of this species separates it from all the other known species of Niesslia (Butin, 1975; Gams, 1971; Hawksworth, 1975; Sathe & Mogarkar, 1975). The ascospore lengths in all the known species lie within a range of 4.5-12 μm. | |||
