Description
Size: Cell length 30-50 µm, breadth 20-60 µm

Color: Red

Red color results from the dominance of the pigments phycoerythrin and phycocyanin; this masks the other pigments, chlorophyll a (no chlorophyll b), beta-caratene and a number of unique xanthophylls.

Thallus form floating reddish patches in the water column, bristly or hair like, regularly dichotomously branched, branches gradually attenuated, branches rather sparse, the terminal pairs forceps shaped, cells towards the lower parts older, primary branches 2-5 times longer than diameter, upper cells are equal or shorter than the diameter, interstices of transverse
zones at the joints somewhat pellucid, lateral wall fibrillose.Vegetative reproduction is rare; asexual reproduction is effected by the formation of various kinds of spores; Sexual reproduction is unique in this group due to their passive, non flagellated sperm cells (spermatia).
