Dumontia contorta is a relatively small epiphytic algae of the sea-shore.

Description[edit]

The thallus grows from a discoid holdfast to a length of about 23 centimetres (9.1 in). The fronds branch irregularly and sparingly.^[2] The branches are hollow, soft and twisted, dark reddish brown in colour which bleach towards the tips, they clearly taper at their junction.^[1]

Reproduction[edit]

The plants are dioecious (sexes separate) with microscopic spermatangia, carposporangia, and tetrasporangia developing in the surface layer, cruciate.^[1]^[3]

Habitat[edit]

Generally epilithic in rock pools of the littoral zone.^[1]

Distribution[edit]

Common around the British Isles. Europe from Russia to Portugal and Canada to United States. In the NW Pacific and Alaska.^[1]^[4]
