Bangia and Conchocelis phases of the rhodophytan alga Bangia fuscopurpurea were examined ultrastructurally. The two phases differed in chromatophore shape, position, and aixangement of thylakoids, pyrenoid structure, position of vacuole(s), quantity of starch, and presenceof pit connections. The Conc Hocetis phase possesses numerous characteristics of the florideophycean red algae and appears structurally more closely alJied to that subclass than to the Bangiophycidae. Our study also demonstrates that the Ultrastructure of the chromatophore of the conchocelis phase does not correspond completely with that described for other florideophycean or bangiophycean algae.
