A total of 12 taxa were identiHed: Boodlea composita (Harv.) F.Brand, Chaetomorpha aerea (Dillwyn) Kütz., Chaetomorpha brachygona Harv., Chaetomorpha ligustica (Kütz.) Kütz., Chaetomorpha vieillardii (Kütz.) M.J.Wynne, Cladophora brasiliana G.Martens, Cladophora laetevirens (Dillwyn) Kütz., Cladophora socialis Kütz., Cladophoropsis membranacea (Bang ex C.Agardh) Bargesen, Dictyosphaeria versluysii Weber Bosse, Rhizoclonium africanum Kütz., and Rhizoclonium riparium (Roth) Harv. The geographic distribution of Cladophora socialis is extended to the South Atlantic, and Chaetomorpha ligustica is an addition to the marine Hora of Bahia.
