SPECIES, AUTHORITY K. ramanujamii (Kumar) Kalgutkar & Jansonius 2000
LOCATION Padappakkara, Quilon District, Kerala State, South India.
ORIG DESCRIPTION* Fungal spores tricellate, inaperturate and fusiform. Size 32-40 x 18-21 µm. Septa 1.6-2 µm thick, with or without a central pore. Central cell large, 11-13 x 16-19 µm, terminal cells smaller, 9-10 µm long, with narrowly rounded ends. Spore wall ± 1.5 µm thick and ornamented with longitudinal ribs (about 2 µm wide) that run full length but are more pronounced on central cell. Furrows 1-2 µm wide.
COMMENTS* Imprimospora ramanujamii closely resembles the 3-celled ribbed spore type described by Ramanujam & Srisailam (1980, pl. 2, fig. 28). Imprimospora tankensis Norris 1986 (fide Jansonius & Hills, 1987: card 4444) is described as having a thinner (0.5 µm) spore wall with unicellate body.

The species is named after Dr. C.G.K. Ramanujam, Hyderabad, India.

K&J REMARKS Imprimospora ramanujamii, as described, does not fit the diagnostic characters of the genus Imprimospora. Imprimospora is unicellular, even if superficially it appears to be septate, with a median band ("cell") that has apertures in the form of pores or fissures. Kalgutkar and Jansonius (2000) consider Imprimospora to be a junior taxonomic synonym of Palaeoamphisphaerella.

Imprimospora ramanujamii is distinctly 3-cellate with two thick septa, while the spore is traversed by prominent full length longitudinal furrows. As currently there is no genus for dispersed fungal spores with these characters, Kalgutkar and Jansonius (2000) propose a new genus Kumarisporites, with K. ramanujamii as its type.
