Chytroeisphaeridia hyalina

hyalina (Raynaud, 1978, p.394–395, pl.2, fig.18) Lentin and Williams, 1981, p.45.  Holotype: Raynaud, 1978, pl.2, fig.18.  Originally Tapeinosphaeridium, subsequently (and now) Chytroeisphaeridia.  Taxonomic junior synonym: Chytroeisphaeridia grossa, according to Riding (1990, p.311).  This combination was not validly published in Riley and Fenton (1980, p.340), since these authors did not reference the basionym.  Age: early-middle Callovian.
