Rhodophyta
members of the Thallophyta division Rhodophyta, in which the chlorophyll is masked by phytocoerythrin. Rhodophytes vary from filamentous forms to those with an extensive thallus and have non-motile gametes.

The algae are further grouped into various phyla: Euglenophyta (euglenids), Chrysophyta (diatoms), Pyrrophyta (dinoflaggelates), Chlorophyta (green algae), Phaeophyta (brown algae), and Rhodophyta (red algae).
Phycobilins are water-soluble pigments, and are therefore found in the cytoplasm, or in the stroma of the chloroplast. They occur only in Cyanobacteria and Rhodophyta.
