Green color individuals of Mazzaella laminarioides were observed growing in a population from the Strait of Magellan. These individuals were cultivated under laboratory conditions in order to determinate if they are effectively green color variants or the green color is a short-term acclimation process. No significant difference in the growth rate between green variants and red wild-type individuals were observed, and the difference of color was maintained during the experiment in laboratory. These results suggest that the green individuals of M. laminarioides found in a population from Strait of Magellan are definitely a green color variant.

Key words:  Green color variant, Gigartinales, Strait of Magellan
