Abstract

All known charophytes from the Devonian and Lower Mississippian sediments of North America are described, illustrated, and referred to eight species distributed among five genera. Representatives of Chovanella, Sycidium, Karpinskya, Moellerina are widely distributed in North America, Europe and Asia; Eochara is at present known only from western Canada. A neotype for Moellerina greenei Ulrich is selected, and the genus Trochiliscus Karpinsky is suppressed as a junior synonym of Moellerina.
