subsp. brevispinum (Davey and Williams, 1966b, p.58, pl.10, fig.10) Lentin and Williams, 1973, p.80. Emendation: Marheinecke, 1992, p.61, as Hystrichosphaeridium proprium subsp. brevispinum. Holotype: Davey and Williams, 1966b, pl.10, fig.10; Bujak et al., 1980, pl.8, figs.10–12; Fauconnier and Masure, 2004, pl.47, figs.1–4. Originally Hystrichosphaeridium tubiferum var. brevispinum, subsequently (and now) Hystrichosphaeridium tubiferum subsp. brevispinum, thirdly Hystrichosphaeridium proprium subsp. brevispinum. Lentin and Williams (1993, p.336) retained this taxon as a subspecies of Hystrichosphaeridium tubiferum. Taxonomic senior synonym: Micrhystridium (as Dapsilidinium?, now Litosphaeridium) fucosum, according to Below (1982c, p.29) — however, Lentin and Williams (1985, p.190) retained Hystrichosphaeridium tubiferum subsp. brevispinum. Age: early Eocene.
