The cell wall has irregularly spaced conical protrusions. There is one large cup-shaped chloroplast. A pyrenoid is located posteriorly. A peripheral stigma is located in the anterior 1/3 of the cell. Two equal flagella are about the length of the cell body. From freshwater pond near Boise, Idaho. Phase contrast.
