This page provides current names for California seaweed species, including those whose names have changed since the publication of Marine Algae of California (Abbott & Hollenberg 1976). Both former names (1976) and current names are provided. This list is organized by group (green, brown, red algae); within each group are genera and species in alphabetical order. California seaweeds discovered or described since 1976 are indicated by an asterisk.
This is a draft of an on-going project. If you have questions or comments, please contact Kathy Ann Miller, University Herbarium, University of California at Berkeley. kathyannmiller@berkeley.edu
