spiculatum (White, 1844, p.87, pl.9, fig.4) Downie and Sarjeant, 1965, p.96.  Holotype: White, 1844, pl.9, fig.4.  Originally Xanthidium tubiferum var. spiculatum (Appendix A), subsequently Hystrichosphaeridium spiculatum, thirdly (and now) Baltisphaeridium spiculatum.  This combination was not validly published in Downie and Sarjeant (1963, p.92), since these authors did not fully reference the basionym.  Age: Late Cretaceous.
