New evidence shows that Corallina sagittata J.V. Lamouroux and Jania sagittata Blainville (Corallinaceae, Corallinales, Rhodophyta) are based on the same type collection. Consequently, when Corallina sagittata is placed in Jania, the correct name is J. sagittata (J.V. Lamouroux) Blainville and not Jania lamourouxiana (Decaisne) J.H. Kim, M.D. Guiry & H.-G. Choi, as recently proposed.
