Original description: [Benson, 1976]:
Description:
Chorate cysts with plate centered hollow processes of varying sizes and morphology. Processes abruptly terminated and of aculeate, denticulate, and recurved-patulate types. Processes reflect tabulation of 4`, 6``, 6c, 5```, 1p, 1````, 4-5s. Archaeopyle precingular (Type P). Cyst wall bilayered, periphragm giving rise to processes. Cingulum indented by processes with flattened bases. Position of sulcus marked by small flexuous processes. Processes composed of fused hyaline fibrils.
