Calliblepharis fimbriata (Greville) Kützing 1843: 404

Thalli complanate, strap-like, up to 25 (30) cm long, flaccid, bright to dark red, branched, markedly frilly. Holdfast bearing short stipe that widens into main axis. Branching opposite, sub-opposite or irregular. Main axis and main branches widest in the middle (usually 8-15 (-20) mm wide), tapering towards both ends, with marginal proliferations or teeth. Structure uniaxial, in cross-section with large un-pigmented medullary cells surrounded by smaller cortical cells. Dioecious, cystocarps in smaller branchlets, protruberant, ostiole absent. Tetrasporangia zonately divided, scattered in outer cortical tissue. This rather pretty species is quite distinctive on account of its soft, almost delicate texture and frilly margins.
