John et al. (2004) cite Polysiphonia myriococca Mont., P. subulata (Ducluz.) J. Agardh, P. violacea (Huds.) Grev. and P. violacea var. subulata (Ducluz.) Hauck as synonyms of this species.
This species was introduced accidentally, probably via fishing baits and shipping, and on multiple occasions, into the Mediterranean (Verlaque et al. 2015: 2011), being first found in the Etang de Prevost (France) in 1988. It is now widely distributed in the Mediterranean. - (5 Nov 2015) - M.D. Guiry
Mid to low intertidal of sand-covered rocks from moderately to extremely wave-exposed sites (Diaz-Tapia & Bárbara 2013). - (27 Jan 2014) - Wendy Guiry
This is a marine species.
(as Polysiphonia fucoides (Hudson) Greville)
English: Black Siphon Weed (Bunker & al. 2010).
Swedish: Fjäderslick (Tolstoy & Österlund 2003).
Cartilaginous, cylindrical, tufted, brownish purple fronds, to 300 mm long (more usually about 70 mm long), from branched rhizoidal holdfast. Branching ± alternate, tripinnate, ramuli with terminal tufts of colourless dichotomous fibrils. Plants perennial, ramuli and branchlets shed in winter, leaving jagged stumps. Large central siphon surrounded by 12-20 pericentral siphons, corticated only at base. Articulations as long as broad in older parts, to 1.5 times as long as broad distally.
On rocks and epiphytic, intertidal at all levels, often in shallow pools and runnels, widely distributed, common.
