Popis: A detailed study of the original material of Dasya ocellata and related taxa revealed that the current concept of the species is not fully coincident with that of its basionym, Ceramium ocellatum. The original material is conserved at LD, and consist of two specimens affixed on the same voucher and these do in fact belong to two different species. One of them, which was selected as the lectotype, fits the current concept of D. ocellata whilst the other corresponds to D. hutchinsiae. Although the former specimen is not apparently the best to fit the protologue, it is not in serious conflict with it, and that choice ensures the traditional usage of the name. Several nomenclatural and historical features related to the name are also discussed. The name Dasya ocellata (Grateloup) Harvey is currently applied to red algae of Ceramiales with the axis simple or very scarcely branched (1� 3 basal lateral branches), all of them strongly corticate. The uniseriate pseudolaterals are straight and long (1000� 1800 mm) and generally with a sharp apical cell. Tetrasporangial stichidia are long (500� 700 mm)
