Common names

(as Chondracanthus acicularis (Roth) Fredericq)
English: Creephorn (Bunker et al. 2010).

Description
Cartilaginous, cylindrical or compressed, purple-red or blackish fronds, sometimes with greenish or whitish spots, to 100 mm long, irregularly bipinnately branched, branches curved, sharply pointed. Base initially discoid, becoming stoloniferous and entangled.

Habitat
On rocks, lower intertidal, generally uncommon but may be locally common on sheltered, silty shores in the lower intertidal, southern and western shores reaching its northern limit on the mid-western Irish coast.

Similar species
Gigartina pistillata (S.G. Gmelin) Stackhouse, an uncommon species except in the lower intertidal of south-western shores north to Pembrokeshire in Wales and Waterford in Ireland, forms pinnately branched ultimate branches and is not stoloniferous. Chondracanthus teedei (Roth) Kützing is brownish red in colour, distinctly compressed, regularly pinnately branched, and occurs in a few localities on the south and west coasts of Britain and Ireland.
