Summary
Cells ofChlamydomyxa montana Lankester photosynthesize within a cyst under bright light and ingest diatoms in an excysted amoeboid form during periods of low light intensity. Cyst cell walls are partially comprised of cellulose and vary in thickness. The cells are multinucleate and intracellular bacteria are closely associated with the nuclei. A pair of centrioles is also present adjacent to individual nuclei. Chloroplasts are numerous and thylakoids are generally organized into bands of three. No endoplasmic reticulum was found surrounding the plastids, nor was a complete girdling lamella ever observed within.C. montana chloroplasts appear to be its own but this protist does not precisely fit into an algal class.
