The zoospores of Coelomycidium simulii are produced by cleavage of the thallus with the aid of early formed flagella beating in the clefts. A nuclear complex (nucleus and nuclear cap) enclosed in a common membrane, a flagellum fixed to the nuclear complex via a rootlet system, and a mitochondrion forming a sensory plate are described. The structure is supported by vacuoles and microtubules. The infection cycle, zoospore formation, and environmental susceptibility during this stage are discussed.
