"brevifurcatum" (Eisenack, 1954a, p.207-208, pl.1, fig.2; text-fig.2) Downie and Sarjeant, 1965, p.88. Holotype: Eisenack, 1954a, pl.1, fig.2. NOW Visbysphaera (Appendix A). Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly (and now) Visbysphaera (Appendix A), fourthly Multiplicisphaeridium (Appendix A). This combination was not validly published in Downie and Sarjeant (1963, p.89), since these authors did not fully reference the basionym. Age: Silurian (Late Llandovery).
Parent: Baltisphaeridium
