An investigation of the life cycle of Caulochytrium gloeosporii Voos and Olive, a parasite of Gloeosporium , has confirmed the existence of an alternation of generations. Zoospores from sessile sporangia may develop vegetatively into similar sporangia or they may function as isogametes, fusing in pairs to produce cysts (zygotes) that give rise to slender‐stalked aerial sporangia. Meiosis is believed to occur in the aerial sporangium, which at germination liberates eight asexual zoospores. The species is homothallic.
