Abstract
Lingappa, Yamuna Ph.D., Purdue University, September, 1957. The Life-History, Development, Sexuality and Host Range of Physoderma pulposum (Wallr.) Karling. Major Professor; Dr. J. S. Karling.Physoderma pulposum is a chytridiaceous fungus parasite of Chenopodium album and Atriplex patula in the vicinity of Purdue University, Lafayette, Indiana. Its life-cycle consists of a repeating, monocentric, eucarpic, epibiotic zoosporangial phase and a polycentric endobioetic resting sporangial phase.The planospores from single sporangia infect the epidermal host cells and give rise to an intramatrical rhizoidal system and an extramatric 1 zoosporangium. This epibiotic phase is continually repeated when conditions are favorable for its development.
