Disphaeria
From Williams et al., 2017:
[Disphaeria, Cookson and Eisenack, 1960a, p. 11; Emendation: Norvick, 1973, p. 45
tax. sr. synonym of Thalassiphora Eisenack and Gocht, 1960, according to Norvick, 1973, and Yun, 1981. Lentin and Williams, 1977, Morgan, 1980, and Cookson and Eisenack, 1982, retained Thalassiphora as a separate genus.
tax. sr. synonym of Subathua Khanna and Sing, 1980, according to Sarkar and Singh, 1988. Lentin and Williams, 1989, accepted the type species of Subathua, S. sahnii, as a tax. jr. synonym of Thalssiphora patula (Williams and Downie, 1966) Stover and Evitt, 1978.
Type species: Disphaeria macropyla, Cookson and Eisenack, 1960a (pl.3, fig.13)] ; emend. Norvick, 1976

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.
