Summary Hesperophycus harveyanus (Decaisne) Setchell & Gardner (Fucaceae, Phaeophyceae), the type and only known species of its genus, is representative of Fucus L., not of Hesperophycus as described by Setchell and Gardner. Hesperophycus is therefore proposed for conservation with Gardner 1842 , on which the generic description was based, as type. The species is redescribed as H. californicus P. C. Silva. It ranges from Santa Cruz, California, to Punta Eugenia, Baja California, but is scarce on the southern California mainland. It occurs on all of the Channel Islands of southern California, but is especially abundant on Santa Catalina and Santa Cruz islands, where it forms an extensive belt in the upper intertidal zone, above Pelvetia.
