Cyanidium (sigh-ann-id-ee-um) is a small coccoid RED alga. Although its colour is exactly the same as that of many prokaryotic blue-green algae, careful scrutiny of the cells shows that the pigments is not distributed throughout the cell, but is within a compartment (filling most of the cell). This is a picture of a culture made from isolates from Nymph Creek and Nymph Lake, thermal sites within Yellowstone Park, and is included to illustrate the colour of the pigment arrays. Photograph by Kathy Sheehan and David Patterson. Images were taken of samples from thermal sites in Yellowstone National Park at the Thermal Biology Institute of Montana State University, August 2001. Image copyright: D. J.
