Palaeohystrichosphaeridium williereae subsp. dameryense Appendix A

"subsp. dameryense" (Dorning, 1981, p.188, pl.2, fig.6) Fensome et al., 1990, p.384.  Holotype: Dorning, 1981, pl.2, fig.6.  NOW Dilatisphaera williereae subsp. dameryensis.  Originally Dilatisphaera dameryensis (Appendix A), subsequently Palaeohystrichosphaeridium willierae subsp. dameryense, thirdly (and now) Dilatisphaera williereae subsp. dameryensis.  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).
