(C. candidus), or the terminal conidium of each chain gives rise to a germinating filament, if it is capable of germinating, while the other cells of the conidial chain produce zoogonidia (C. Portulaca;). After the swarming is finished the zoogonidia become firmly attached to the cuticle of the host, invest themselves with a thin cell-wall, and, in the case of Peronospora infestans, put out a delicate germinating filament directly into an epidermal cell, piercing through its outer wall.
