The monotypic fossil genus, Diploneurospora, was described by Jain & Gupta (1970) from the Early Miocene (23–16 mya) sediments of Padappakkara, Kollam District, Kerala, India. The genus includes two-celled, uniseriate, elliptical ascospores with uneven margins. The upper cell is prominent, and the spore wall is dark brown, thick, and sculptured with longitudinal ribs. The smaller lower cell is hyaline, appendage-like and with a faint rib sculpture. According to Jain & Gupta (1970), the single-celled ascospores of the extant genus Neurospora are similar to the two-celled fossil ascospore of Diploneurospora. Only one species is listed in Index Fungorum (2023) under this genus.
Type species: Diploneurospora tewarii Jain & Gupta.
