Endophragm finely granular and attached at numerous points to a tightly folded, completely enveloping periphragm. Archeopyle apical, probably type [tA]; operculum usually missing. Archeopyle shape resembling that of other species of Aprobolocysta.

Absence of an apical horn and wrinkled cyst surface distinguish A. galeata from Batioladinium micropodum (Eisenack & Cookson) Brideaux 1975. In A. bipartita the periphragm is only folded in precingular and postcingular areas.
