| Abstract: | The Japanese red alga Grateloupia lanceolata (Okamura) Kawaguchi was discovered in southern California at Santa Catalina Island in spring 2003 and April 2008 and in central California at the mouth of the Elkhorn Slough in Moss Landing in May, June and July of 2008. The morphology of thalli from both localities agrees with published figures. Sequences from the rbc L gene and the nuclear marker, internal transcribed spacer-1 from Californian G. lanceolata were identical to those from two specimens of G. lanceolata introduced to the Thau Lagoon, Mediterranean France and a specimen from Japan. It is likely that the import of oysters for mariculture played a role in its introduction into California. |
