Taxonomic notes
According to Gargiulo (in Furnari et al., 1999), themost records referred as Gracilariopsis longissima for Adriatic shores of Italy are probably based on specimens belonging to species of Gracilaria.

Specimens reported as Fucus verrucosus, Fucus confervoides, Gracilaria verrucosa and Gracilaria confervoides - in fact, all terete Gracilaria - from the NE Atlantic and elsewhere require individual examination to determine whether they belong to Gracilaria or Gracilariopsis, and then a decision as to which species is in question. - (18 Sep 2010) - M.D. Guiry

Distributional notes
Records of Gracilariopsis lemaneiformis (Bory) Dawson from Britain (Fredericq & Hommersand 1989b) were rejected by Steentoft et al. (1995) and the plants in question referred to this species. See also Steentoft & Farnham (1997). Guiry (1997) notes that this species is also known from France and Spain. See Saunders & Kraft (1994).

General environment
This is a marine species.
