Arthrospira
Arthrospira is a genus of free-floating filamentous cyanobacteria characterized by cylindrical, multicellular trichomes in an open left-hand helix. A dietary supplement is made from A. platensis and A. maxima, known as spirulina. The A. maxima and A. platensis species were once classified in the genus Spirulina. Although the introduction of two separate genera is now generally accepted, there has been much dispute in the past and the resulting taxonomical confusion is tremendous.
