SUMMARY The betaine lipid DGTA differentiates between two species of Ectocarpus : it is present in E. fasciculatus Harvey, and lacking in E. siliculosus (Dillwyn) Lyngbye, Two ectocarpoid isolates from the coast of Chile, which could not be identified to species level, were found to belong to opposite DGTA types. Culture experiments showed that these plants were sporophytes. Their meiospores produced gametophytes of the species predicted by the lipid analysis. Promoted by this new approach, a sexual population of Ectocarpus fasciculatus has been detected for the first time in the Pacific Ocean.
