Abstract

Synura (Synuraceae, Chrysophyceae) includes some of the more common and conspicuous planktonic algal forms in lowa. This genus, with its covering of characteristic overlapping siliceous scales is representative of the Synuraceae. Since 1955 published identifications of species in this family by specialists have not been considered accurate unless they are based on electron microscopy of scales. However, little effort has been made to correlate light microscopy with electron microscopy. In this paper scales are illustrated with transmssion and scanning electron micrographs as well as light micrographs. Four of the most common Synura species are discussed. Three of them, S. uvella Ehrenberg, S. echinulata Korshikov, and S. spinosa Korshikov have not previously been identified from Iowa material on the basis of electron microscopy. The fourth species, S. petersenii Korshikov, has been reported once previously.
