 endobioticum (Schilb.) Percival, the cause of potato wart disease. New Phytol. 18: 90-91. 

 1919. — A preliminary statement. The resting sporangium gives rise to numerous uniciliate 

 zoospores, which infect the growing potato. Subsequent development of the zoospore leads 

 to the production of smaller zoospores which are said to be facultative gametes, which may 

 infect the host without fusion. Infection by a zygote leads to the formation of a resting spor- 

 angium. — /. F. Lewis.
