Silicofilosea

Assulina (ass-you-line-a) a testate amoeba with a subapical mouth located on the ventral surface of the slightly flattened lorica. Common in mosses. Phase contrast.

Protaspis (pro-tass-piss) A very common but little studied genus of gliding flagellates, two flagella inserted one in front of the other in a shallow ventral depression near the front of the cell. One flagellum trails behind the cell, one sweeps in front of the cell. There are caps (dictyosomes?) over the nucleus and these can be seen as two lines leading away from the site of flagellar insertion. Protaspis can produce pseudopodia and may eat diatoms. This individual has starchy inclusions. Phase contrast.

Euglypha (you-g-lie-fa) is a widespread and common testate amoeba. This one was found in a sample of moss, and this is a habitat in which testate amoebae are common. The aperture is to the top of the image. The test is made up of scale arranged a bit like fish scales, and their are marginal spine scales. This test no longer contains an amoeba. Phase contrast.

Protaspis (pro-tass-piss) A very common but little studied genus of gliding flagellates, two flagella inserted one in front of the other in a shallow ventral depression near the front of the cell. One flagellum trails behind the cell, one sweeps in front of the cell. There are caps (dictyosomes?) over the nucleus and these can be seen as two lines leading away from the site of flagellar insertion. Protaspis can produce pseudopodia and may eat diatoms. This individual has starchy inclusions. Phase contrast.

Paulinella (paul-in-ella) is a testate amoeba but this species is distinguished by the presence of (usually two) curved endosymbiotic blue green algae. The small aperture of the lorica is to the top of the image. Differential interference contrast.
