Morphology remarks:

The vesicle outline is elongated subtriangular to elliptical with a single process at one (apical) pole of the long axis and four to eight processes of variable length clustered around the antapical pole. The wall of both vesicle and processes is thin and bears a finely granular ornament. The processes are mostly hollow with generally angular proximal contacts and taper distally to pointed tips. The process cavity is in communication with that of the vesicle. Some of the smallest processes may be solid. No excystment openings were observed.
