"Oligosphaeridium reniforme" (Tasch in Tasch et al., 1964, p.193, pl.2, fig.6) Davey, 1969a, p.148.
TYPE: Holotype: Tasch et al., 1964, pl.2, fig.6. HISTORY: Originally Hystrichosphaeridium, subsequently Oligosphaeridium. SYNONYM(S): Taxonomic senior synonym: Hystrichosphaeridium (now Oligosphaeridium) albertense, by implication in Stover and Evitt (1978, p.69), who considered Hystrichosphaeridium reniforme to be a taxonomic junior synonym of Hystrichosphaeridium (subsequently Oligosphaeridium) irregulare, which is now a taxonomic junior synonym of Hystrichosphaeridium (now Oligosphaeridium) albertense. COMMENTS: This combination was not validly published in Davey and Williams (1966b, p.77), since these authors did not fully reference the basionym. AGE: Albian.
