Hystrichosphaeridium oligocanthum W.Wetzel 1952
Now Cleistosphaeridium?. Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly (and now) Cleistosphaeridium?, fourthly Laticavodinium.
Holotype: W. Wetzel, 1952, pl.A, fig.8; Sarjeant, 1984, pl.2, figs.4-5, text-fig.2
Locus typicus: Kiel district, Germany
Stratum typicum: Danian
Translation W.Wetzel, 1952: Sarjeant, 1984
Original Diagnosis: W. Wetzel, 1952, p. 403
"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".
