Polysiphonia stricta is a small red marine alga in the Division Rhodophyta.
Polysiphonia stricta forms dense clumps of branching axes. The plants grow to 25 cm high.[2]
P. stricta grows as small tufts of much branched tufts, growing to no more than 25 cm high.[2] The axes are erect, ecorticate, with 4 periaxial cells growing from prostrate axes. All 4 of the periaxial cells are of the same length.[2][3]
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.[2]
Epizoic and epiphytic in the low littoral to 20 m.[2]
Found around the British Isles, the West Atlantic and American Atlantic.[2]
