Description
Red colour 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 erect or undulating, delicate, fluffy, soft; branching alternate, generally sparse; branches slippery, slimy, long, gracefull, densely covered by fine branchlets, base often denuded; holdfast small, inconspicuous, disc-like. Main branches corticated; branchlets filamentous.

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).
