Polysiphonia elongata is a small red alga which, unlike some other species of Polysiphonia, does not grow as tufts. It has erect cylindrical main branches and is densely branched growing to a height of 30 cm. The main branches bear lateral branches, each branch consists of a central axes of cells with four periaxial cells.
Trichia, Fuligo, Lycogales, Stemonitis- often found in cool, damp, shaded environments; body mass called plasmodium is coenocytic; usually resembles a mass of slime; if food is scarce & light is available, will grow resistant reproductive sporangia; if not, will dry into sclerotium & be dormant til conditions change; are multinucleate Supergroup Bikonta.
