Hystrichosphaeridium oligacanthum ssp. oligacanthum
Hystrichosphaeridium oligocanthum ssp. oligocanthum W.Wetzel 1952
Autonym, now redundant.
Originally Hystrichosphaeridium oligacanthum ssp. oligacanthum, subsequently Baltisphaeridium oligacanthum ssp. oligacanthum, thirdly Cleistosphaeridium? oligacanthum ssp. oligacanthum.
Holotype: W. Wetzel, 1952, pl.A, fig.8
Locus typicus: Kiel district, Germany
Stratum typicum: Danian
Translation W.Wetzel, 1952: Sarjeant, 1984
Original Diagnosis: W. Wetzel, 1952, p. 403: Hystrichosphaeridium oligocanthum
"Principal characteristics . .. are relatively stately dimensions, thick-walled capsule and processes which produce only insignificant, narrow tubes distally [and] which, as a result of their "softness" [lack of rigidity] may be bent into curves. The number of processes may vary considerably, but is perhaps in most cases to be denoted as moderate. Curvature of the processes is common, but not regular".
