References in the literature to the silica-scaled chrysophytes of Iowa are few and, since the advent of the electron microscope, identifications of taxa in this group are no longer considered valid without accompanying electron micrographs. Using scanning electron microscopy for critical identifications, eight taxa genera of the Synuraceae are reported here including the first known report of the genus Paraphysomonas from Iowa. From the other two genera, Mallomonas and Synura, only one of the taxa in this paper, Mallomonas pseudocoronata, has been reported from Iowa previously. Mallomonas acaroides var. striatula, M. tonsurata, M. tonsurata var. alpina, M. teilingii, M. pseudocorcnata, …
