Berecibar, Estibaliz; Wynne, Michael J.; Santos, Rui
A collection of four tetrasporangiate specimens of Gulsonia nodulosa (Ercegović) Feldmann et Feldm.-Maz. (Ceramiaceae, Rhodophyta) has been made from Sines and Cabo Raso, Portugal. This represents the first reported occurrence of this species outside of the Mediterranean, where it has been relatively well known since its original description (as Crouania annulata) from Naples, Italy, by Berthold (1882).
