Like some other Chytridiales, "Synchytrium endobioticum" develops no mycelium. Glynne's first major work was studying Synchytrium endobioticum, the cause of potato wart disease. Synchytrium endobioticum is a chytrid fungus that causes the potato wart disease, or black scab. "Synchytrium endobioticum" is an obligate parasite that infects several plants of the genus "Solanum". Chytrids may also infect plant species; in particular, "Synchytrium endobioticum" is an important potato pathogen.
