Nomenclatural notes
New name: later starting- point basionym (INA). - (21 August 2014) - G.M. Guiry
This name is listed as Phormidium autumnale Trevisan ex Gomont 1892 by Strunecky et al. (2013: 1176) but Gomont (1892:187-189) does not attribute the name to Trevisan. - (21 February 2014) - M.D. Guiry
INA notes: "Gomont (1892) treated Phormidium vulgare as a synonym of P. autumnalis, so M. vulgaris cannot be based on a Gomont name. Microcoleus vulgaris must be lectotypified with a specimen not nomenclaturally entangled with P. autumnale." - (22 April 2014) - M.D. Guiry
Taxonomic note
It exists also Phormidium autumnale (C. Agardh) Trevisan 1844, Alg. Udin. 20, with Basionym Oscillatoria autumnalis C. Agardh 1822. - (21 September 2024) - Salvador Valenzuela Miranda
