Common names

(as Gymnogongrus crenulatus (Turner) J.Agardh)
English: Norwegian Fan Weed (Bunker et al. 2010).

Description
Cartilaginous, fleshy, flattened, dark red fronds, to 100 mm high, with short cylindrical stipe from basal disc. Repeatedly dichotomous, branches strap-shaped, apices rounded, often paler than rest of frond. Reproductive structures appear as external, wart-like excescenses.

Habitat
Epilithic, lower littoral in pools and emergent, and sublittoral to 13 m, tolerant of sand cover; plants typically encrusted with species of Bryozoa, Foraminifera and calcareous algae (Dixon & Irvine 1977: 218, 219). On sand-covered rocks, lower intertidal, southern and western coasts, often locally abundant.
