Abstract

Chrysophycean cysts (stomatocysts, statospores) from Lake Baikal and Irkutsk Reservoir, Siberia, Russia have been investigated by means of scanning electron microscopy for the first time. The paper contains descriptions and illustrations of 7 particularly distinctive forms. Five of the cyst types described here are new to the literature. Two are very similar to cysts previously described from lake sediments in North America, but differ in details of surface ornamentation and cyst collar construction.
