Phthanoperidinium eocenicum

Phthanoperidinium? eocenicum (Cookson and Eisenack, 1965a, p.119-120, pl.11, figs.1-5) Lentin and Williams, 1973, p.113.

TYPE: Holotype: Cookson and Eisenack, 1965a, pl.11, figs.1-2.

HISTORY: Originally Peridinium (Appendix B), subsequently (and now) Phthanoperidinium?. Questionable assignment: Lentin and Williams (1973, p.113).

COMMENTS: Stover and Evitt (1978, p.119) considered Phthanoperidinium stockmansii and Phthanoperidinium resistente to be possible taxonomic junior synonyms of Phthanoperidinium? eocenicum. Eaton (1976, p.294) also proposed this combination.
