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.

Labyrinthula (lab-ee-rin-thule-a). Amazin things, labyrinthulids. There are only a couple of genera of these stramenopiles. Labyrinthula is usually associated with dead and decaying marine plants - such as eel grass. The organisms secrete an ectoplasmic network through which the spindle shaped cells can migrate. Periodically they give rise to flagellated cells. Differential interference contrast.

Labyrinthuloides (lab-ee-rin-thule-oid-ees). Labyrinthuloides is a thraustochytrid - very closely related to the labyrinthulids. The trophic form is a usually a large mass of cytoplasm giving rise to a system of fine rhizoid-like ecotoplasmic extensions. This image is from a culture growing on agar showing cells and some of the ectoplasmic strands. Phase contrast.

Diplophys, small spherical cell with a clear, yellow or orange lipid drop (or drops) in the centre of the cell, and two tufts of fine pseudopodia extending from the opposing poles of the cell. Phase contrast micrograph.
