Fucus anomalus Pallas (1766) is shown to be the oldest legitimate, valid and available name for the brown alga currently known as Sporochnus gaertnera C.Agardh. Thus, the binomial Sporochnus anomalus (Pallas) comb. nov. is proposed. A nomenclatural and taxonomic historical background on this alga is also provided.
