Nitschkia phaeospora W. H. Hsieh et al., Mycol. Res. 102: 228-229. 1998.

 Description: Ascomata 350-400 μm wide, 300-400 μm high, superficial gregarious, scattered to rarely grouped, dark brown, cup-shaped, setose,coriaceous, non ostiolate with an apical ‘Quellkörper’ composed of hyaline, inconspicuous, thin-walled, mucilaginous cells. Setae 30-150 × 9-10 μm, dark brown, aseptate to septate, pointed at the apex. Peridium 30-70 μm wide, composed of 7.5-15.0 μm wide, dark brown, thick-walled pseudoparenchymatous cells with 1-2 μm wide ‘Munk pores’. Dark brown, 5-7 μm thick septate hyphae form a subiculum at the base of the ascomata and penetrated the host cells. Paraphyses up to 1 μm wide, filiform, hyaline, unbranched, evanescent. Asci 50-60 μm × 9-10 μm in the spore bearing part, long stalk, stalk up to 60 μm long and 4 μm wide, arising from a basal hymenium, unitunicate, eight-spored evanescent, without apical ring. Ascospores 13-18 × 4-6 μm, ovoid, brown, 1-septate in the middle, septum dark and thickened, not constricted smooth, overlapping biseriate or biseriate above an uniseriate below inside ascus.

 Note: Most species in Nitschkia G. H. Otth ex P. Karst. have hyaline ascospores (Nannfeldt, 1975) but four, N. archeri (Berk.) Subram. & Sekar, N. pulneyensis Subram. & Sekar, N. sundara Subram. & Sekar and N. thekkadyensis Subram. & Sekar have hyaline to brown ascospores. The ascospores in these four species are significantly larger with a maximumlength varying from 30-45 μm (Subramanian & Sekar, 1990).
