"subsp. ramosum" (Ehrenberg, 1837b, pl.1, fig.15) Eisenack, 1931, p.112.  Holotype: not designated.  Lectotype: Ehrenberg, 1837b, pl.1, fig.15, designated by Davey and Williams (1966a, p.32).  Combination not validly published: specific name not validly published.  NOW Spiniferites.  Originally Xanthidium ramosum (Appendix A), subsequently (and now) Spiniferites ramosus, thirdly Ovum hispidum subsp. ramosum (combination not validly published), fourthly Hystrichosphaera ramosa, fifthly Bion ramosum (Appendix A).  Taxonomic junior synonyms: Xanthidium (as Hystrichosphaera) furcatum, according to Davey and Williams (1966a, p.29–33); Galea korykos and Hystrichosphaeridium echinoides, both according to Sarjeant (1983, p.91–92); Areoligera birama, according to Morgenroth (1968, p.550); Geodia? tripunctata, by implication in Sarjeant (1964a, p.175), who considered Geodia? tripunctata to be a taxonomic junior synonym of Hystrichosphaera furcata; Hystrichosphaera (as Spiniferites) bulloidea, according to Harland (1977b, p.101–102) — however, Lentin and Williams (1981, p.259) retained Hystrichosphaera (as Spiniferites) bulloidea; Homotryblium distinctum, according to Jain and Garg (1982, p.69), who considered Homotryblium distinctum to be a taxonomic junior synonym of Spiniferites ramosus subsp. ramosus.  Motile equivalent: Gonyaulax spinifera (Claparède and Lachmann, 1859) Diesing, 1866, according to Dodge (1989, p.289).  Downie and Sarjeant (1965, p.174) attributed this combination to Lohmann (1904); however, the combination was apparently not proposed in this latter publication.  Age: Late Cretaceous.
