Abstract: Oospores and oogonia of P. dissotocum, P. myriotylum, P. irregulare, and one isolate of P. ultimum increased in diameter after being subcultured for 30 mo. Oospores and oogonia of P. aphanidermatum and one isolate of P. ultimum decreased in diameter during this period. Sporangia of P. irregulare increased in diameter and of two isolates of P. ultimum decreased in diameter during this period. The taxonomic value of reproductive cell diameter in the genus Pythium is discussed.
