SPECIES, AUTHORITY I. sahnii Kalgutkar 1997, p. 216, pl. 2, fig. 18.

ORIG DESCRIPTION* Spores subspherical to broadly ovate with subcircular to oval outline, inaperturate, smooth, brown to mid-brown. Spore wall fairly thin. Spore diameter 20-27 µm.
COMMENTS* Inapertisporites circularis Sheffy & Dilcher 1971 has a thicker spore wall and smaller size. I. cystoides Ambwani 1983 and I. major Ke & Shi 1978 have circular spores more than 60 µm in diameter, and spore walls with a thickness of more than 4 µm. In I. laevigatus Rouse 1959 the incurved region of the wall acts as a germinal aperture.
