Oocystaceae

Portrait of the planktonic trebouxiophyte alga, Tetrastrum staurogeniaeforme (Schröder) Lemmermann.The colonies consist of four ellipsoid cells with four to six short spinous projections from the each cell surface. several four-celled colonies may join together to form compound colonie (compound coenobia). Each cell has one plastid and one pyrenoid.Collected from a freshwater pond near Boise,Idaho. July 2005.DIC.

Green algae live in a mucus ball. Phase contrast microscopy.

Portrait of the planktonic green alga Chodatella longiseta (Lemmerman,1898;Printz). This genus differs from the very similar Franceia in having long slender spinous processes limited to the poles of the ovoid cell. There is no gelatinous layer. There are two chloroplasts each with a prominent pyrenoid (seen in this image). Collected from a freshwater pond near Boise, Idaho June 2004. DIC optics.

Chodatella citriformis containing 8 autospores, sampled from shore water of Lake Kinneret in March 2006. This Chlorophyte (Chlorococcales) can be found in the plankton of the lake at most times of the year, particularly in May-June, but is never dominant.

Eremosphaera viridis bears lots of chloroplasts, each with a central pyrenoid body. The brace like marks amidst the chloroplasts represent the amylum shells of the pyrenoids. High resolution multi layer image assembled of 15 Eremosphaera shots (manually stacked). See zip archive for details.  Sample from sphagnum pond situated in the northern alpine region of Austria near Salzburg. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.
