Dictyota cyanoloma Tronholm, De Clerck, A.Gómez-Garreta & Rull Lluch, 2010
The type species used to describe the genus is Dictyota dichotoma (Hudson) J.V. Lamouroux.
The species name Dictyota cyanoloma “cyanoloma” means: cyanos (Greek) = blue color; loma (Greek) = fringe, edge, i.e., with a blue edge.
Description: Thallus 7.6–8.2 cm long, erect, attached to the substrate by blunt, velvety rhizoids. Color in situ dark brown with blue-iridescent margins in fertile specimens and entirely blue-iridescent in infertile specimens. Branched, with the tips of the branches rounded to blunt at the top.
Dictyota cyanoloma stands out in harbors and bays due to its characteristic light blue iridescent margins. This species was originally described in Europe, but later studies have shown that it was introduced from Australia. The current range of Dictyota cyanoloma includes southern Australia and the northeastern Atlantic, including the Mediterranean Sea and the Macaronesian Islands. The presence of Dictyota cyanoloma in Southern California has been confirmed by molecular genetic sequences.
Dictyota cyanoloma appears to be limited (so far) in the United States to the California coast from San Diego Bay in the south to Santa Catalina Island and Long Beach Harbor in the north. A species distribution model suggests a gradually decreasing habitat suitability north of the Southern California Bay and high suitability in Baja California, including the Gulf of California. Finally, the widespread
