Note: Phormidium ambiguum was proposed as a substitute name for Amphithrix amoena Kützing in consideration of the prior existence of P. amoenum Kützing (1843b: 192; type locality: not specified). Drouet (1968: 232, 246), after examining the holotype of A. amoena (in L), assigned it to Microcoleus vaginatus (Vaucher) Gomont.
