Florideophyceae, demoted to subclass Florideae in some classification systems, is a class of red algae.[2] It is sometimes merged with the Bangiophyceae into the Rhodophyceae, leaving the subclass Florideae in use.[3] They were once thought to be the only algae to bear pit connections,[4] but these have since been found in the filamentous stage of the Bangiaceae.[5]
"Florideophyceae" is still used by some authorities.[6]
Once thought only to exhibit apical growth, some genera grow by intercalary growth.[5] Most, but not all, genera have three phases to the life cycle.[5]
