Cleistosphaeridium oligacanthum ssp. stella
Cleistosphaeridium oligocanthum ssp. stella, (W. Wetzel, 1952), Lentin and Williams, 1973
Now Surculosphaeridium? phoenix ssp. stella. Originally Hystrichosphaeridium oligacanthum ssp. stella, subsequently Baltisphaeridium oligacanthum ssp. stella, thirdly Cleistosphaeridium? oligacanthum ssp. stella, fourthly (and now) Surculosphaeridium phoenix? ssp. stella.
Holotype: W. Wetzel, 1952, pl.A, fig.4
Locus typicus: Kiel district, Germany
Stratum typicum: Paleocene

Original diagnosis as Hystrichosphaeridium oligocanthum ssp. stella: [W. Wetzel, 1952, p. 403]: (Translation: Sarjeant, 1984):
Diagnosis:
Some specimens, which in other attributes do not differ from the typical species, are distinguishable from it in that the distal ends of the processes develop into two sideways-directed prongs (and thereby suggest more the usual structure of hystrichosphere processes). Also no noteworthy curving of the processes was observed.
