The last genus does not cause the development of tumors by the host, while all the others cause con- spicuous hypertrophies. Only Plasmodiophora and Spongospora cause disease of economic importance. An interpretation of the life cycle of the Plasmodiophroaceae is not yet possible. Except for the unconfirmed work of Prowazek and of Osborn, the location of caryogamy is unknown. Similarly the relation of the sporonts to plasmodia needs more careful investigation. Because of this obscurity, a discussion of the relationships of the Plasmodiophor-.
