"Palaeohystrichosphaeridium williereae subsp. dameryense" (Dorning, 1981, p.188, pl.2, fig.6) Fensome et al., 1990, p.384.
TYPE: Holotype: Dorning, 1981, pl.2, fig.6. HISTORY: NOW: Dilatisphaera williereae subsp. dameryensis. Originally Dilatisphaera dameryensis (Appendix A), subsequently Palaeohystrichosphaeridium willierae subsp. dameryense, thirdly (and now) Dilatisphaera williereae subsp. dameryensis. COMMENTS: The combination Palaeohystrichosphaeridium williereae subsp. dameryense was not validly published in Eiserhardt (1986, p.182) since that author did not specify the taxonomic rank; he gave the citation "Palaeohystrichosphaeridium williereae dameryensis." AGE: Silurian (Llandovery).
