Salpingoeca tuba Kent, 1880. Cells are elongate, about 10 - 15 microns long and located in a cylindrical lorica that is round at the base. The basal part of the lorica has filamentous threads (arrow). One flagellum emerges at the anterior end of the cell and is about the cell length, and its tip is thin. The nucleus lies near the centre of the cell. The lorica attaches to the substrate by its posterior end.
