Polysiphonia simulans is a small marine alga in the division Rhodophyta.
This small alga is no more than 8 cm long. It appears as a tuft of irregularly branched erect axes. The branches show 10 periaxial cells forming a collar around a central axis without cortication. The pericentral cells are all of the same length. Rhizoids are attached to the lower periaxial cells.[1]
Tetraspores have been recorded in the final branches.
Recorded from the south coast of England, Ireland and the Channel Islands. Also recorded from north-west France.[1][2] Occurs southwards to Morocco.[3]
