Description
Cartilaginous, dark purplish-red, red, yellowish or greenish fronds to 150 mm high, gametophyte plants are often iridescent under water when in good condition. Stipe compressed, narrow, expanding gradually to a flat, repeatedly dichotomously branched frond, in tufts from a discoid holdfast. Axils rounded, apices blunt or subacute, frond thicker in centre than margins. Very variable in breadth of segments. Very variable in branching, colour and thickness.
Habitat
On rocks, lower intertidal and shallow subtidal, in pools in the mid-intertidal in some locations; widely distributed in the north western and north eastern Atlantic, often abundant and zone-forming at low water.
Key Characteristics
Regular dichotomous branching; cartilaginous feel to the fronds; absence of papillate cystocarps and channeling.

Nomenclatural note
Replacement name for Fucus crispus Linnaeus, 1767, nom. illeg., priority for Fucus crispus Hudson, 1762 (Art. 58.1). - (18 November 2015) - M.D. Guiry
Taxonomic note
John et al. (2004) treat Chondrus crispus var. lonchophorus as a synonym of Chondrus crispus var. crispus but this rquires further study. - (11 May 2006) - G.M. Guiry
Distributional note
The occurrence of this species in the Canary islands is doubtful; see comments in Price et al. (1986). Skottsberg (1953: 545, footnote) was of the opinion, certainly correct, that a record from the Antarctic Peninsula is not this species (see Papenfuss, 1964: 40). John et al. (2004) note that all records are considered doubtful by Price et al. (1986) and Haroun et al. (2002). - (11 May 2006) - G.M. Guiry
