Polysiphonia stricta is a small marine algae.

Polysiphonia stricta forms dense clumps of branching axes. The plants grow to 25 cm high.[1]

Description

P. stricta grows as small tufts of much branched tufts, growing to no more than 25 cm high.[1] The axes are erect, ecorticate, with 4 periaxial cells growing from prostrate axes. All 4 of the periaxial cells are of the same length.[1][2]

Reproduction

Spermatangial branchlets are formed in clusters at the apices. Cystocarps are on short stalks and are urceolate. The tetraspores are in series in the final branches.[1].

Habitat

Epizoic and epiphytic in the low littoral to 20 m.[1]

Distribution

Found around the British Isles, the West Atlantic and American Atlantic.[1]
