Disphaeria
From Fensome et al., 2019:
Disphaeria, Cookson and Eisenack, 1960a, p.11.
Emendation: Norvick, 1973, p.45.
Taxonomic junior synonyms: Thalassiphora, according to Norvick (1973, p.45) -- however, Lentin and Williams (1985, p.353) retained Thalassiphora; Subathua, by implication in Sarkar and Singh (1988, p.41), who transferred the "type species" of Subathua, Subathua sahnii, to Disphaeria -- however, Lentin and Williams (1989, p.354) accepted Subathua sahnii as a taxonomic junior synonym of Adnatosphaeridium (as Thalassiphora) patulum.
Type: Cookson and Eisenack, 1960a, pl.3, fig.13, as Disphaeria macropyla.

Original description: [Cookson and Eisenack, 1960]:
Description:
Shell approximately three-quaters of a sphere, with a large opening and a partially enclosed capsule.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Emended description:
Norvick, 1973:
Diagnosis:
Pterate cyst with the endophragm and periphragm in contact on the dorsal surface only. Inner capsule ellipsoidal or spherical, granular or without
surface ornament. The periphragm may be smooth, granular, or echinate and is expanded into a lamellar wing, which is attached on the dorsal side to the inner capsule. The ventral side of the inner body may or may not be partially overlapped by the-recurved margin of the lamellar wing. Traces of the cingulum and of the tabulation may or may not be represented by lines of periphragmic folds. The archaeopyle is formed by the loss of a single reflected precingular plate area, either P or P/P.
