Fucus capillaceus S.G.Gmelin

Type Information
Type locality: Locus, Mare mediterraneum [Mediterranean Sea]; (Gmelin 1768: 146) Lectotype: original illustration (Gmelin , 1768, pl. 15 fig.1). (epitype) (Womersley & Guiry 1994: 139)

Origin of Species Name
Adjective (Latin), capillarg, hair-like, thread-like (Stearn 1983).

General Environment
This is a marine species.

Cartilaginous, dark purplish-red, flattened fronds, 2 mm wide, to 200 mm high. Pinnate or bipinnate, often bare at base, branches opposite or alternate, often tapering at both ends; frequently give a 'Christmas-tree' appearance. Fronds in loose tuft from a rhizoidal base.

In large pools and lagoons in the lower intertidal and shallow subtidal, widely distributed on south and south-western shores, never common.

Key Characteristics
Larger, darker and more purplish-red than Gelidium pusillum or G. pulchellum; normally, Pterocladia is not found fringing the edges of pools like the latter. Main axes are generally more flattened and apices more obtuse than G. pulchellum.

Similar Species
Gelidium sesquipedale is known only a restricted number of localities in SW Britain (mainly Cornwall) although it is much commoner in N France; this species is larger and relatively less flattened.
