Stentor amethystinus - a smallish brown member of the genus. The brown colour comes from a combination of dark red pigment granules which lie in rows between the kineties and may also lie within the cytoplasm, and endosymbiotic green algae. This image shows the pigment granules among kineties in the oral region.
