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

Type information
Type locality: Nuweiba, Sinai, Red Sea (Lipkin & Silva 2002: 41). Holotype: W. Schimper; L 937.117.229 (Prud'homme van Reine 1982: 203).

Taxonomic notes
According to Silva et al. (1996) the taxon Sphacelaria furcigera var. princeps apparently lies within the circumspection of this species but has not yet been transferred or reduced to synonymy.

Habitat notes
Widespread in warm and temperate seas. Usually on Sargassum and Turbinaria, forming dense velvety growths on the stalks, at times intermingled with, but less abundant than, S. tribuloides; also on Padina boergesenii and lithophytic (Lipkin & Silva 2002). Epilithic in rock pools and epiphytic on larger algae (especially Caulocystis uvifera; also on Cystoseira and on Cladostephus) and on seagrasses (Womersely 1987). - (14 Jun 2010) - Wendy Guiry

General environment
This is a marine species.
