Areosphaeridium pectiniforme

"pectiniforme" (Gerlach, 1961, p.195–196, pl.28, fig.14; text-fig.18) Stover and Evitt, 1978, p.20.  Emendations: Sarjeant, 1984b, p.83–84,86, as Areosphaeridium pectiniforme; Stover and Williams, 1995, p.114, as Enneadocysta pectiniformis.  Holotype: Gerlach, 1961, pl.28, fig.14; Sarjeant, 1984b, pl.1, fig.2; pl.4, fig.2; Fauconnier and Masure, 2004, pl.7, figs.4–5.  NOW Enneadocysta.  Originally Baltisphaeridium (Appendix A), subsequently Cleistosphaeridium, thirdly Areosphaeridium, fourthly Areosphaeridium?, fifthly (and now) Enneadocysta.  Taxonomic junior synonym: Areosphaeridium (now Enneadocysta) multicornutum, according to Sarjeant (1984b, p.83–84,86) — however, Stover and Williams (1995, p.112) retained Areosphaeridium (as Enneadocysta) multicornutum.  Questionable assignment: Stover and Evitt (1978, p.20) — however, Sarjeant (1984b, p.83) included this species in Areosphaeridium without question.  Age: middle Oligocene.
