Pervosphaeridium truncigerum

"Pervosphaeridium? truncigerum" (Deflandre, 1937b, p.71-72, pl.13 [al. pl.10], figs.6-7) Yun Hyesu, 1981, p.27.

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. Questionable assignment: Stover and Williams (1987, p.176).

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

AGE: Senonian.
