American winter flounder, Pseudopleuronectes americanus , Collected in the New York‐New Jersey bay complex, contained cysts in the intestinal tract which were subsequently identified as the microsporidan Glugea stephani . These fish represent 13 collections taken at approximately monthly intervals over a one and a half year period. The winter flounder varied in size from 8 to 33 cm and consequently represented a fish population of diverse age. During this study, a total of 1840 apparently healthy fish were dissected and examined for the presence of Glugea cysts , with an overall parasite infection rate of 6.63%. There was no correlation between size of the fish and percentage of infection. This percentage represents the mean carrying rate of this parasite in the fish population, since these are the fish that have survived the initial infection. This report extends the reported host range to the New York‐New Jersey area. As a further aid in the characterization of G. stephani , we have included ultrastructural details of the spore morphology.
