A new species of the red algal genus Woelkerlingia,W. sterreri C. W. Schneid. & M. J. Wynne, is described from a single collection made in Bermuda. The collection contained male and female (dioecious) individuals as well as tetrasporangia and polysporangia on sporophytes. The Bermudian species is compared with and distinguished from W. minuta of the Mediterreanean Sea, up to now the only other species recognized in the genus, as well as other members of the Spermothamnieae. Tiffaniella gorgonea is excluded from the flora of Bermuda after looking at Collins and Hervey material on which the historic record was solely based.
