Multiplicisphaeridium borracherosum (Cramer, 1964) Eisenack et al., 1973

Originally Baltisphaeridium (an acritarch genus), subsequently (and now) Multiplicisphaeridium; see also Hystrichosphaeridium (combination not validly published). This combination was not validly published in Lister, 1970 since
that author did not clearly use the name Multiplicisphaeridium borracherosum.
Holotype: Cramer, 1964, pl.1, fig.11
