Chrysophycean algae are a diverse and often abundant group of primarily freshwater phytoplankton, characterized by the endogenous formation of siliceous cysts or stomatocysts (also called statospores or statocysts). Cyst morphology is highly variable, but believed to be species-specific.
Recently, cysts have received considerable attention from phycologists and especially paleoecologists who wish to use these indicators for assessments of environmental change. Nonetheless, attempts at using cysts have often been hampered by taxonomic problems.
This Atlas dispels some of...

Chrysophytes are a diverse and often abundant group of primarily freshwater algae that are characterized by the endogenous formation of siliceous cysts or stomatocysts (also called statospores or statocysts). Cyst morphology is highly variable, but believed to be species-specific. Cysts have continued to receive attention from phycologists and especially paleoecologists, who use these indicators for assessments of environmental change.
In this volume, we have compiled descriptions, using both scanning electron and light microscopy, as well as line drawings, for 176 new cyst descriptions....
