A hitherto undescribed species of Scyphidia has been shown to infest the skin of brown trout. However, it is incapable of colonizing the skin of American brook trout, even when these fish are co‐cultivated with heavily infested brown trout. Possible mechanisms accounting for this host/parasite specificity are discussed.
