Gymnogongrus crenulatus J. Agardh
For a long timeknown as G. norvegicus, but this name,
in the strict sense, has been shown to refer to
Chondrus crispus and not to this entity
Description: Cartilaginous, fleshy, flattened,
dark red fronds, 60-100 mm high, with short cylindrical stipe
arising from basal disc. Repeatedly dichotomous, branches
strap-shaped, apices blunt-rounded (see picture below), often
noticeably paler than the rest of frond (above). Margins of
frond irregular and sculpted. Reproductive structures appear as
external, wart-like excescenses (see below).
Habitat: On sand-covered rocks, lower
intertidal, southern and western coasts, often locally abundant.
Often turning an unhealthy colour with prolonged exposure during
particularly low tides.
