This is a marine species.
Type locality: Bayonne [Pyrénées-Atlantiques, France] (Dixon & Price 1981: 136). Not specified: (Dixon & Price 1981: 136). Notes: The existence of Roth herbarium is at present a matter of doubt. Usually, it is assumed to have been lost in the bombing of the Berlin-Dahlem museum (Pilger, 1953); this seems true for specimens of Ceramium roseum. There is a specimen at LD (Herb. Alg. Agardh 18466), labelled "‘Ceramium roseum Roth Bayonne dedit Roth ipse non rosea Dillw."’ in C. Agardh'’s hand, but the status of this specimen is uncertain. Subsequent interpretations (Dillwyn, 1802; Smith, 1802) were based on a specimen collected in 1797 by Sowerby at Yarmouth and sent to Roth for comment by Dawson Turner. This specimen, which Roth identified as Ceramium roseum, passed to K (now at BM-K), with a duplicate of the original Sowerby collection at BM. Although not part of the type collection, these specimens help to unravel subsequent interpretations of this taxon, of which there have been several. The BM-K specimen is here designated as of neotype status.
