Ovum hispidum subsp. tubiferum

"Ovum hispidum subsp. tubiferum" (Ehrenberg, 1838, pl.1, fig.16) Downie and Sarjeant, 1965, p.174.

EMENDATION: Davey and Williams, 1966b, p.56-58.

TYPE: Holotype: Ehrenberg, 1838, pl.1, fig.16.

STATUS: Combination not validly published: specific name not validly published, basionym not fully referenced, and combination not intended.

HISTORY: NOW: Hystrichosphaeridium tubiferum. Originally Xanthidium tubiferum (Appendix A), subsequently Hystrichosphaera tubifera (combination not validly published), thirdly (and now) Hystrichosphaeridium tubiferum, fourthly Ovum hispidum subsp. tubiferum (combination not validly published).

SYNONYM(S): Taxonomic junior synonym: Xanthidium (as Hystrichokolpoma) bulbosum, according to Stover and Evitt (1978, p.55) - however, Lentin and Williams (1989, p.134) retained Xanthidium (as Hystrichokolpoma) bulbosum.

COMMENTS: Downie and Sarjeant (1965, p.174) attributed this combination to Lohmann (1904); however, the combination was apparently not proposed in that publication.

AGE: Late Cretaceous?
