Micrographs of cyanobacteria

This section contains images of cyanobacteria under magnification for general identification purposes. They are not intended to be used for specific algal identification and are not indicated for recommendations of treatment or other control methods. Natural coloration may be altered by preservation or optics.

Note: Planktic Anabaena-morphotypes with gas vesicles have been transferred into the new genus Dolichospermum, as represented in the below micrographs.
