Gymnochlora (jim-know-clore-a), one of the amoeboid algae but like other members of the chlorarachniophytes the plastids result from a secondary endosymbiotic event involving a eukaryotic green alga, a nucleomorph is present. With bright green plastids and fine irregular pseudopodia. Differential interference microscopy.

Euglypha (you-gligh-fah) cristata has an elongate shell that is composed of siliceous scales. The point of the shell shows a characteristic tuft of three to eight spines. The circular aperture is bordered by a single row of five to six denticulate scales. Pseudopodia are rarely extended. Differential interference contrast.

Sainouron (sigh-noo-ron) is a small gliding flagellate from soils. Body elliptical, one trailing flagellum, rarely with an anterior flagellum. This image shows a subapical insertion of the flagellum. The cell shape is somewhat distorted (swollen). Phase contrast.

Portrait of isolated cell with bright green plastids and fine granular pseudopodia. Differential interference microscopy.

Sainouron (sigh-noo-ron) is a small gliding flagellate from soils. Body elliptical, one trailing flagellum, rarely with an anterior flagellum. The flagellum can here be seen to be acronematic (the far end is thinner). Phase contrast.

Clathrulina, one of the desmothoracid protists. Stalk and lorica. Bright field.

Hellkesimastix (hell-keys-ee-ma-stix) a small flagellate, originally reported from soils. With one trailing flagellum and one other short flagellum. Probably,y a cercomonad. Phase contrast micrograph.

Euglypha (you-gligh-fah) filifera has an elongate shell that is composed of oval siliceous scales. The 15 micron long spines pointed out from the entire lateral edge of the shell. The nucleus is visible in the posterior third of the cell. Differential interference contrast.
-
Helkesimastix faecicola Woodcock and Lapage, 1915. Cells ovoid or drawn out, 5-10 microns long and about two-thirds as wide as long. A single flagellum, 2-3 times cell length, inserts at or slightly below the cell apex, is attached along the length of the body and also adheres to the substratum as cells glided. The nucleus is central, and there is a single contractile vacuole towards the posterior. Cells are slightly flexible and the cytoplasm is sometimes drawn out along the trailing flagellum.

Clathrulina (cla-through-line-a), showing head region and included amoeboid cell. This image shows the stiffened pseudopodia which led the desmothoracids to be regarded as a type of heliozoon. Differential interference contrast.
-
Euglypha (you-gligh-fah) filifera has an elongate shell that is composed of oval siliceous scales. The 15 micron long spines pointed out from the entire lateral edge of the shell. View of the aperture surrounded by denticulate scales. Long filopodia extended from the aperture. The aperture measures 6 microns in diameter. Differential interference contrast.
-
Abollifer prolabens Voers, 1992. The cell is about 8-12 x 10-20 microns It is ovoid-oval and dorso-ventrally flattened with a deep anterior or depression into which the flagellum inserts. The sides of this depression are swollen. The cell surface is rigid and granulated, the cell appears opaque and probably has a pellicle. The cell moves by gliding, but it may detach from the substrate and jerk through the water with an irregular sinusoidal flagellar beat, a second shorter trailing flagellum is sometimes present.
-
Clathrulina, desmothoracid flagellate, traditionally regarded as a kind of heliozoon. The trophic cell lives as an amoeba within a stalked lorica, and pseudopodia extend from the lorica. This reproduces to form a flagellated cell which leaves the lorica and establishes itself elsewhere. Phase contrast.
-
Euglypha (you-gligh-fah) filifera has an elongate shell that is composed of oval siliceous scales. The 15 micron long spines pointed out from the entire lateral edge of the shell. Image of Euglypha filifera lorica. The denticulate scales which border the circular aperture are visible. Each plate is measuring 6 X 8 microns on average. Differential interference contrast.
-
Spongomonas (spong-owe-moan-ass), is a solitary or colonial spongomonad flagellate, in which the cells are located within a more or less globular matrix formed from adhering small globules of mucilage. Many cells were dislodged while this sample was being prepared. Phase contrast.
-
Clathrulina, one of the desmothoracid protists. Traditionally classified as the heliozoa because of the star-shaped appearance of the cell, but the heliozoa have always been a rag-bag of unrelated organisms. Desmothoracids may adopt one of several forms. A mature trophont (feeding form) is an amoeboid organism with stiffened arms. It lives in an spherical (ish) organic lorica which has large openings. The chamber is borned on a hollow stalk, and several stalked loricae may be joined end to end or in a branching arrangement. The stiffened pseudopodia extend out of the openings to capture food. Division leads to the formation of flagellated cells one or all progeny vacate the lorica, swim around and then settle as an amoeba. The amoeba secrete a stalk and mucus, and the mucus is shaped and accretes to form a lorica. The lorica strengthens and thickens with age. This image is of a cell that has recently begun the process of creating a lorica. Differential interference contrast.

Euglypha (you-gligh-fah) filifera has an elongate shell that is composed of oval siliceous scales. The 15 micron long spines pointed out from the entire lateral edge of the shell. Apical view on the shell of Euglypha filifera. From this view it is evident that the shell is compressed and that the spines arise from the lateral edge of the shell. Differential interference contrast.
-
Spongomonas (spong-owe-moan-ass), is a solitary or colonial spongomonad flagellate, in which the cells are located within a more or less globular matrix formed from adhering small globules of mucilage. In this case the colony has formed at the end of some extraneous fibre. Phase contrast.
