Colony-forming morphology is one of the characteristics of the species "Aphanizomenon flos-aquae"; conversely "Aphanizomenon" are not known to form colonies. Algologists Li and Carmichael noted colony formation, or lack thereof, and other morphologic distinctions when comparing "Aphanizomenon flos-aquae" with "Aphanizomenon". Their genetic comparison of "Aphanizomenon flos-aquae" to other species in the genus "Aphanizomenon" indicates dissimilarity between "Aphanizomenon flos-aquae" and "Aphanizomenon" species. Cyanobacteria have been a staple in the diets of many cultures and have been used for both food and commerce by indigenous
