"subsp. fissum" (Sannemann, 1955, p.331, pl.6, fig.9; text-figs.14a–c) Fensome et al., 1990, p.355. Holotype: Sannemann, 1955, pl.6, fig.9. NOW Aldridgeisphaera? robusta subsp. fissa (Appendix A). Originally Hystrichosphaeridium robustum subsp. fissum, subsequently Baltisphaeridium robustum subsp. fissum (combination illegitimate, Appendix A), thirdly Multiplicisphaeridium robustum subsp. fissum, fourthly (and now) Aldridgeisphaera? robusta subsp. fissa (Appendix A). This combination was not validly published in Eisenack et al. (1973, p.781) since these authors did not clearly indicate the taxonomic rank. Age: Devonian (late Givetian).
