Florideophyceae was a class of red algae. It is now merged with the Bangiaceae into the Rhodophyceae. They were once thought to be the only algae to bear pit connections,[1] but these have since been found in the filamentous stage of the Bangiacae.[2]
Once thought only to exhibit apical growth, some genera grow by intercalary growth.[2] Most, but not all, genera have three phases to the life cycle.[2]

The class contains the following orders:
- Acrochaetiales
