cantharellus (Brosius, 1963, p.40-41, pl.6, fig.1; text-fig.2, nos.11a-c) Gocht, 1969, p.45. Holotype: Brosius, 1963, pl.6, fig.1; Fensome et al., 1993a, fig.1 - p.1021. Originally Hystrichosphaeridium, subsequently (and now) Cordosphaeridium, thirdly Tityrosphaeridium. This species was retained in Cordosphaeridium by Edwards (2001, p.G19). This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.91), since these authors did not fully reference the basionym. N.I.A. Age: Late Oligocene.
