Description:

Phyllomitus (file-owe-mite-us) undulans Stein, 1878. Cells are about 11 - 12 microns long and have two flagella that adhere to each other. The cells are pointed anteriorly and posteriorly. The flagella arise at the anterior end of the cell. The flagella appear to be similar in length, about 3 times longer than the cell, and undulate. The pellicle is smooth and the nucleus is located on the mid-anterior part of the cell. Cytoplasmic strands may be seen from the posterior end. The cells may attach to the substrate by the posterior end of the cell. Rarely observed.
