Cordosphaeridium truncigerum

"Cordosphaeridium truncigerum" (Deflandre, 1937b, p.71-72, pl.13 (al. pl.10), figs.6-7) de Coninck, 1975, p.80.

TYPE: Holotype: Deflandre, 1937b, pl.13 (al. pl.10), fig.6.

HISTORY: NOW: Raetiaedinium. Originally Hystrichosphaeridium, subsequently Litosphaeridium?, thirdly Cordosphaeridium, fourthly Exochosphaeridium, fifthly Pervosphaeridium, sixthly Tityrosphaeridium?, seventhly Florentinia, eighthly Pervosphaeridium?, ninthly (and now) Raetiaedinium.

SYNONYM(S): Taxonomic senior synonym: Xanthidium (now Hystrichokolpoma) crassipes, by implication in Yun Hyesu (1981, p.27), who considered Cordosphaeridium (as Pervosphaeridium) truncigerum to be the senior name - however, Lentin and Williams (1985, p.282) retained Cordosphaeridium (as Pervosphaeridium) truncigerum.

AGE: Senonian.
