subsp. callosum ([[Sannemann, 1955]], p.325-326, pl.1, figs.1-4,7; pl.3, figs.2-5,10; pl.4, figs.3-9; pl.6, figs.11-12; text-figs.2a-d) [[Fensome et al., 1990]], p.87.  Holotype: [[Sannemann, 1955]], pl.4, fig.3.  Originally [[Hystrichosphaeridium brevispinosum subsp. callosum|Hystrichosphaeridium brevispinosum]] subsp. [[Hystrichosphaeridium brevispinosum subsp. callosum|callosum]], subsequently [[Buedingiisphaeridium brevispinosum subsp. callosum Appendix A|Buedingiisphaeridium brevispinosum]] subsp. [[Buedingiisphaeridium brevispinosum subsp. callosum Appendix A|callosum]] (combination not validly published, Appendix A), thirdly (and now) Baltisphaeridium brevispinosum subsp. callosum.  This combination was not validly published in [[Downie and Sarjeant, 1963|Downie and Sarjeant (1963]] p.90), since these authors did not fully reference the basionym, nor was it validly published in [[Eisenack et al., 1973|Eisenack et al. (1973]], p.79-80), since these authors did not give a clear indication of taxonomic rank.  Le Herissé in Ribecai and Tongiorgi (1999, p.124) considered this taxon and [[Baltisphaeridium brevispinosum subsp. castaneoides Appendix A|Baltisphaeridium brevispinosum]] subsp. [[Baltisphaeridium brevispinosum subsp. castaneoides Appendix A|castaneoides]] to be "... related to mazuelloids or muellerisphaerids (mineralized microfossils)" and not conspecific with [[Hystrichosphaeridium brevispinosum|Hystrichosphaeridium]] (now [[Pachysphaeridium brevispinosum Appendix A|Pachysphaeridium]]) [[Hystrichosphaeridium brevispinosum|brevispinosum]], but no new taxonomic assignations were proposed.  We feel that, although the species has been transferred to [[Pachysphaeridium Appendix A|Pachysphaeridium]], since this Index does not treat acritarchs or mineralized microfossils in detail, it would be inappropriate for us to make taxonomic proposals here; hence we leave two subspecies (and the autonym) "in limbo".  Age: Devonian (Late Givetian).
