Abstract
A chytridiaceous fungus was found parasitic in the roots of cucurbitaceous plants in Varanasi during December–March. Morphology and development of the vegetative and reproductive structures and its parasitism confined to the cucurbitaceous host plants as revealed by inoculation studies, indicated it as a variant isolate of Olpidium brassicae (Woronin) Dangeard. Association of the pathogen with mosaic virus-infected cucurbit vines indicated its possible role in the transmission of pumpkin and bottle gourd mosaic viruses.
