Florideophyceae, demoted to subclass Floridae in some classification systems, is a class of red algae.[2] It is sometimes merged with the Bangiaceae 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 Bangiacae.[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]

[edit] Classification
There are various classification schemes; see Red algae. One option is to use the following:
[edit] Subclass Hildenbrandiophycidae
[edit] Subclass Nemaliophycidae
[edit] Subclass Corallinophycidae
The subclass Corallinophycidae was introduced in 2007.[7]
[edit] Subclass Ahnfeltiophycidae
[edit] Subclass Rhodymeniophycidae
- Bonnemaisoniales
- Gigartinales
- Gelidiales
- Gracilariales
- Halymeniales
- Rhodymeniales
- Nemastomatales
- Plocamiales
- Ceramiales
