Rhizomonas setigera (Pavillard, 1916) Patterson et al., 1993. Cells found adhering to detritus, with one flagellum up to 25 microns long. The cell body is 6-20 microns in diameter and often embedded in mucus. Cells may produce elongate pseudopodia.

Amphitrema (am-fee-tree-ma) a testate amoeba with an organic test with (unusually) two apertures at opposite poles of the test. This empty test found among moss at the margins of the lake. Differential interference contrast.

Phyllomitus vesiculosus Larsen and Patterson, 1990. Sac-shaped body, 11-15 microns long, slightly dorso-ventrally flattened. Two flagella arising from large anterior depression, anterior flagellum extending in front of the cell with a long sweeping curve, the posterior flagellum trailing behind. The nucleus lies near the cell center, adjacent to the base of the flagella, a rod or bar lies against one anterior side of the nucleus. The outer region of the cytoplasm is highly vesiculate, vesicles with granules. Moves by swimming, frequently in the immediate vicinity of the substratum, with the posterior flagellum dragging against the substratum.

Portrait of Bicosoeca petiolata, a colorless loricate flagellate (synonymous with Poteriodendron petiolatum). This species is colonial with daughter cells forming stalks attached to the mother lorica after division. Most species of this genus are solitary. The cells of this colony are retracted with the long hair bearing flagellum tightly coiled on the anterior end of the cell (seen well in the cell on your left in this image). The second short smooth flagellum is directed posteriorly attaching the cell to its lorica. The lorica is organic. From fresh water marsh with Typha (Cattail) near Boise, Idaho. Differential interference contrast.
