SYNOPSIS. Haplosporidium mytilovum Field, 1924, a sporozoan (?) parasite in the ova of the mussel Mytilus edulis L., is found to be morphologically similar to, and deemed to be congeneric with, the type species of genus Chytridiopsis Schneider, C. socius S., 1884, in beetles. It is compared also with the only other reported species of Chytridiopsis in a mollusc, C. ovicola Léger and Hollande, 1917, in ova of the European oyster, Ostrea edulis L. These two parasites in ova of bivalve molluscs are much alike but, since they seem to have some slight morphological differences, it would be premature to conclude that they belong to the same species. Chytridiopsis , a genus of uncertain affinities, has been considered by various authors to be related to the Chytridiales, the Haplosporida, the Mycetozoa or the Microsporida. New evidence favors the hypothesis that it is microsporidian in nature, although proof in the form of a clearly demonstrated polar filament has not yet been produced.
