Uroglena volvox, Ochromonadaceae.Collected from a pond on the isle of Nordstrand (North Sea). The image was built up using several photomicrographic frames with manual stacking technique. The images were taken using Zeiss Universal with Canon EOS 70D.For high-resolution images please ask postmaster@protisten.de.

Chromulina (crumb-you-line-a) nebulosa, a small chrysophyte (stramenopiles) with a single emergent flagellum. A second short flagellum is visible because cell division is beginning to occur (note the two chloroplasts) and a second flagellum has formed. -Phase contrast microscopy.

Anthophysa (ann-though-fie-sa) is a colonial heterotrophic stramenopile (chrysophyte). Normally ball-shaped aggregates of cells are borne at the ends of brown stalks of an irregularly branching tree-like colony. In this case, the cells have broken away from the stalk. Phase contrast.

Anthophysa vegetans (Muller) Stein, 1878. Cells are wide at the anterior and at one side of the anterior end is a site where food is taken in, and the two flagella (one longer one shorter) insert to the side of this. The posterior tip of the cell extendS into a fine protoplasmic filament of variable length and many cells are usually united at their bases into spherical or hemispherical colonies, and these may either be free-swimming or attached to the substrate by means of a stalk which is coloured brown and is often branched. The stalk nearest the cells is usually narrower and transparent, becoming thickened distally by the deposition of iron and manganese compounds, bacteria are embedded in it throughout its length and can be seen clearly close to the colony.
