Taxonomic studies on the family Pyrocystaceae are scarce because of the group’s special life cycle and complicated taxonomic history. In this study, a detailed literature review of Pyrocystaceae is presented, and cysts of 11 species belonging to Pyrocystaceae are studied using morphological taxonomy methods. We believe that one species should be moved to genus Dissodinium, the remaining 10 species (including 2 varieties and 2 formas) are more reasonably kept in genus Pyrocystis. We also present a morphological description of each species. Furthermore, we believe that the taxonomic relationships between Dissodinium pseudolunula and Pyrocystis lunula, P. elegans and P. robusta require further study.
