Osmundea sanctarum sp. nov. (Ceramiales, Rhodophyta) from the southwestern Atlantic Ocean
An ongoing phycological survey in the Laje de Santos Marine State Park (LSMSP) of São Paulo in southeastern Brazil revealed a previously undescribed species of Osmundea (Rhodophyta, Rhodomelaceae), which was found in the subtidal zone at a depth of 7 to 20 m. Morphological studies conducted on Osmun...
