Disphaerogena
From Fensome et al., 2019:
Disphaerogena, Wetzel, 1933b, p.51.
Emendation: Sarjeant, 1985b, p.140–141.
Taxonomic junior synonyms: Cyclapophysis, according to Sarjeant (1985b, p.140–141); Plethysyrinx, by implication in Stover and Williams
(1987, p.179), who considered Plethysyrinx to be a taxonomic junior synonym of Cyclapophysis. Stover and Evitt (1978, p.292) suggested that this is possibly a radiolarian genus.
Type: Wetzel, 1933b, pl.4, fig.34, as Disphaerogena carposphaeropsis.

Original Description: [O.Wetzel, 1933]: (Translation: Norris and Sarjeant, 1965, p. 26):
Description:
Shell with irregular outer trellis work round the central sphere.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Emended description:
Sarjeant, 1985:
Description:
Proximochorate to chorate, skolochorate cysts, of spheroidal to ovoidal or subpolygonal ambitus. Distinct apical and antapical processes are
present, of variable absolute and relative length; these are surrounded by fibrous processes. The precingular and postcingular processes bend
towards the cingulum, their tips linked by short trabeculae or fusing to form an equatorial tunnel round the cyst, though this may be interrupted
at the sulcus. Paratabulation 4`, 6", ?0c, 6-?7", ?1p, 1````. Archaeopyle single-plate precingular, type P, formed by loss of paraplate 3``.
