"Baltisphaeridium meson" (Eisenack, 1955, p.179) Downie and Sarjeant, 1965, p.92.
TYPE: Holotype: Eisenack, 1954a, pl.1, fig.3. HISTORY: NOW: Visbysphaera mesa (Appendix A). Originally Hystrichosphaeridium intermedium (name illegitimate), subsequently Hystrichosphaeridium meson, thirdly Baltisphaeridium meson, fourthly (and now) Visbysphaera mesa (Appendix A), fifthly Multiplicisphaeridium meson (Appendix A). SYNONYM(S): Taxonomic junior synonym: Baltisphaeridium (subsequently Multiplicisphaeridium) micropilare Cramer, 1970, an acritarch species, according to Ye Xiaorong (1984, p.42). COMMENTS: Hystrichosphaeridium meson is the substitute name for Hystrichosphaeridium intermedium Eisenack, 1954a, p.208, pl.1, figs.3,9; text-figs.3-4 (an illegitimate name). This combination was not validly published in Downie (1959, p.60 and 1963, p.641) and Downie and Sarjeant (1963, p.90), since these authors did not fully reference the basionym. AGE: Silurian (Late Llandovery-Late Ludlow).
