Two new species of Hystichokolpoma (Pyrrhophyta) are described from the Aquia Formation (Upper Paleocene) of Virginia and Maryland. H. tumescens is characterized by a large, bulbous antapical process, and H. mentitum by a main body which in size, general appearance, and outlines of process bases resembles specimens of Eisenackia. With its delicate processes removed, H. mentitum is believed to masquerade as Eisenackia.
