Compositosphaeridium polonicum (Górka 1965) Lentin and Williams 1981

?polonicum (Górka, 1965, p.306-307, pl.3, figs.5-6) Lentin and Williams, 1981, p.53.  Emendations: Erkmen and Sarjeant, 1980, p.68, as Compositosphaeridium polonicum; Courtinat, 1989, p.164, as Compositosphaeridium polonicum - however, see Stancliffe and Sarjeant (1990, p.203).  Holotype: Górka, 1965, pl.3, fig.5.  Originally Hystrichosphaeridium, subsequently Compositosphaeridium Erkmen and Sarjeant (combination illegitimate), thirdly Compositosphaeridium Dodekova, fourthly (and now) Compositosphaeridium? Dodekova.  Questionable assignment: Masure in Fauconnier and Masure (2004, p.138).  Taxonomic junior synonyms: Hystrichosphaeridium (subsequently Compositosphaeridium) costatum, according to Beju (1971, p.292); Compositosphaeridium bulgaricum, according to Dodekova (1990, p.9) - however, Stancliffe and Sarjeant (1990, p.203) retained Compositosphaeridium bulgaricum and Masure in Fauconnier and Masure (2004, p.137) retained Compositosphaeridium costatum.  If the synonymy of Compositosphaeridium costatum with Compositosphaeridium? polonicum were to be followed, the nomenclatural type of the genus Compositosphaeridium Dodekova would remain the holotype of Compositosphaeridium costatum.  Age: Oxfordian.
