"?fucosum" (Valensi, 1955a, p.40; text-fig.2b) Davey and Williams, 1969, p.6. Holotype: Valensi, 1955a, text-fig.2b; Fauconnier and Masure, 2004, pl.52, figs.8–11. NOW Litosphaeridium. Originally Micrhystridium, subsequently Hystrichosphaeridium, thirdly Polysphaeridium?, fourthly Dapsilidinium?, fifthly (and now) Litosphaeridium. Questionable assignment: Davey and Williams (1969, p.6). Taxonomic junior synonyms: Hystrichosphaeridium tubiferum var. brevispinum, according to Below (1982c, p.29) — however, Lentin and Williams (1985, p.190) retained Hystrichosphaeridium tubiferum var. brevispinum (as Hystrichosphaeridium tubiferum subsp. brevispinum); Hystrichosphaeridium (as and now Litosphaeridium) arundum, according to Below (1982c, p.29) — however, Lentin and Williams (1985, p.227) retained Litosphaeridium arundum. This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.95), since these authors did not fully reference the basionym. Age: Late Cretaceous.
