Abstract A new species of fungus, for which time name Saprolegnia invaderis is proposed, was found in fingerling trout at the Leetown (West Virginia) hatchery. Infection occurs through the alimentary tract from which the fungus grows out through the body cavity and the abdominal wall to the exterior, where zoospores and chlamydospores are formed. Growth of the hyphae through the abdominal wall occurs only after the death of the host. A short technical description of the parasite is included.
