Synurids

Mallomonas (ma-la-moan-ass) is a synurophyte alga, traditionally regarded as a chrysophyte or related to the chrysophytes, but distinguished by the presence of extracellular siliceous scales. This genus has large chlorophyll a and c containing plastids, an apical flagellum, and a coating of slipper shaped scales each of which has a long projecting spine. Differential interference contrast.

Synura sphagnicola, a colonial chrysophyte. Synonymous with Skadovskiella. Cells are joined at their posterior ends in the center of the colony. Cells are ovoid with two golden chloroplasts. There are two equal flagella less than 1 cell length. Siliceous scales with a unique ring form from which there is a rod-like projection cover the cell. A detached scale is seen in the center of this image. The scale structure is diagnostic for the species. A stigma is absent. Large vacuoles containing the glucopyranoside storage polymer, chrysolaminarin (leucosin) accumulate in the cytoplasm . The colonies swim with a slow rolling motion.From a polysaprobic temporary freshwater farm pond near Boise, Idaho. Differential interference contrast.Differential interference contrast optics.

Synura uvella.Scale bar indicates 25 m.Collected from a pond on the isle of Hiddensee (German Baltic Sea). The image was built up using several photomicrographic frames with manual stacking technique. The images were taken using Zeiss Universal with Olympus C7070 CCD camera.For high-resolution images please ask postmaster@protisten.de.

Mallomonas annulata.Monadic species of Synurophyceae. Cell is covered by siliceous scales. Second flagellum is not visible. The scale bar indicates 10 m. From the algae culture of the University Duisburg-Essen (Germany), strain WA 18K-M. This image was taken using Zeiss Axioplan with DSLR Canon 600D.For high-resolution images please ask postmaster@protisten.de.

Synura sphagnicola can be preferentially found in sphagnum ponds. Typical are the reddish oil droplets they bear in plasma.Sample from sphagnum pond Dosenmoor near Neumuenster (Schleswig-Holstein, Germany). This image was taken using Zeiss Universal with Olympus C7070 CCD camera. For high-resolution images please ask postmaster@protisten.de.

This genus has large chlorophyll a and c containing plastids, an apical flagellum, and a coating of slipper shaped scales each of which has a long projecting spine. This image is a detail of the empty periplast (coating of scales and spines) and showing the two kinds of scales which make up the periplast. Differential interference contrast.
