Polysiphonia is a red algae, polysiphonous and usually well branched, with some plants reaching a length of about 30 cm. They are attached by rhizoids or haptera to a rocky surface or other alga. The thallus (tissue) consists of fine branched filaments each with a central axial filament supporting pericentral cells. The number of these pericentral cells (4–24) is used in identification. Polysiphonia elongata shows a central axial cell with 4 periaxial cells with cortical cells growing o… WebThis page was last edited on 11 February 2024, at 14:36.

Polysiphonia stricta forms dense clumps of branching axes. The plants grow to 25 cm high. See more P. stricta grows as small tufts of much branched tufts, growing to no more than 25 cm high. The axes are erect, ecorticate, with 4 periaxial cells growing from prostrate axes. All 4 of the periaxial cells are of the same length. See more Spermatangial branchlets are formed in clusters at the apices. Cystocarps are on wide stalks and are urceolate. The tetraspores are in series in the final branches. See more Epizoic and epiphytic in the low littoral to 20 m. See more Found around the British Isles, the West Atlantic and American Atlantic. See more
