Abstract
Two new species of the Lagenidiales endoparasitic on the nematode Rhabditis are reported from Ontario soils. In Myzocytium lenticulare the biflagellate zoospores encyst at any point on the cuticle of the host and penetrate directly through the wall. Sexual reproduction in this species is by oogamy. The antheridial protoplast migrates through a pore in the adjacent wall and fuses with the oogonial protoplast to produce a thick-walled reticulate oospore. In Lagenidium caudatum large biflagellate zoospores encyst at or near the body orifices of the host. Many of the zoospores possess a distinct tail-like appendage. Germination tubes from the encysted zoospores penetrate the body orifices to infect the host. The thallus in this species is distinctive in being composed of narrow, irregular hyphae which fill the host. No sexual stage is known.
