Distributional notes
According to Bird et al. (1986), the correct name for the species reported as Gracilaria debilis in the tropical western Atlantic is G. cornea J. Agardh (Hydropuntia cornea). [see Taylor 1960, 1969 and Fredericq & Norris 1985 records for tropical western Atlantic]. - (31 May 2010) - Wendy Guiry

Habitat notes
Bird et al. (1986) note that this species thrives in moderately exposed areas with clear, well-circulated water and is found from the intertidal zone to 38 m deep (Pereira et al. 1981). - (31 May 2010) - Wendy Guiry
