Common names

(as Polysiphonia lanosa (Linnaeus) Tandy)
English: Wrack Siphon Weed (Bunker & al. 2010).

Cartilaginous, cylindrical, densely tufted, dark brown fronds, to 75 mm long, attached by creeping rhizoids with branches penetrating host plant. Repeatedly pseudodichotomously branched, apices pointed, widely forked. Large central siphon with 12-24 pericentral siphons, ecorticate, articulations shorter than broad.

Hemiparasitic on Ascophyllum nodosum, more rarely on Fucus vesiculosus, never directly on rock (appearances can be deceptive) sheltered mid-tidal, generally distributed, usually abundant where Ascophyllum occurs.
