The type species (lectotype) of the genus Gracilaria is Gracilaria compressa (C.Agardh) Greville.

Status of name
This name is of an entity that is currently accepted taxonomically.

Basionym
Gigartina conferta Schousboe ex Montagne

Type locality: Cape Spartel, Morocco (Gargiulo, De Masi & Tripodi 1992: 59). Type: P.K.A. Schousboe; herb. Thuret, PC (Gargiulo, De Masi & Tripodi 1992: 59). Notes: Isotype: PC-Herb. Thuret.

Homotypic Synonym(s)
Gigartina conferta Schousboe ex Montagne 1839
Plocaria conferta (Schousboe ex Montagne) Montagne 1846
Hypnea conferta (Schousboe ex Montagne) Kützing 1849
Cordylecladia conferta (Schousboe ex Montagne) J.Agardh 1852

Nomenclatural notes
Gargiulo et al. (1992: 59) cite Gracilaria conferta (Schousboe ex Montagne) J. Feldmann & G. Feldmann 1943: 240), but the combination was previously made by MOntagne (1846). - (2 Jun 2010) - Wendy Guiry

Distributional notes
A recently published study (F. Weinberger et al. 2010) has shown that records of G. conferta from Israel are most certainly wrong and result from misidentification of another species of Gracilaria. The authors consider that there is currently no evidence of the presence of this entity in the eastern Mediterranean. - (17 Nov 2010) - M.D. Guiry

General environment
This is a marine species.
