Morphological Characteristics

The coenobium is of 4,8, (16) cells. The cells are much longer than broad, cylindrical, spindle, cone- shaped, or elongated with rounded ends, usually straight or slightly curved, radiating from a common centre. The chloroplast is parietal with one usually invisible pyrenoid; cell end and usually cell basis hyaline.
