Abstract
A new genus and species of chytrid fungi, parasitizing Ophryoscolecidae, is described. Its spores are similar to the "peg-formed organisms" of Kirby. It is pointed out that some hyperparasitic microorganisms, hitherto classified as Microsporidia, but lacking essential characters of this order, are probably chytrid fungi, related to Sagittospora cameroni gen. et sp. nova.
