A REVISION OF THE SPECIES OF PORPHYRA (RHODOPHYTA, BANGIALES) OCCURRING IN BRITISH-COLUMBIA AND ADJACENT WATERS

Starch gel electrophoresis of proteins of Porphyra species occurring in British Columbia and nearby areas has provided new data on species identities. One new species is described. Porphyra kurogii (formerly identified as North Pacific P. purpurea), and its eastern Pacific distribution limit is extended from northern to southern British Columbia. Porphyra maculosa is recognized to be a taxonomic synonym of P. fucicola; new distribution records are provided. Porphyra cuneiformis is the correct name for specimens formerly identified as P. miniata in the area, and P. occidentalis is the correct name for most local specimens of P. "variegata. " A key to the 21 species and 2 subspecies of Porphyra currently recognized in Oregon, Washington, British Columbia, and southeast Alaska is provided. The key includes the recently described P. mumfordii, P. fallax ssp. fallax, and P. fallax ssp. conwayae.
