Nemalion helminthoides is a small marine alga in the division Rhodophyta.
This is a fairly large erect alga which grows to no more than 0.4 m long. The frond is erect with a solid axis. It is very mucilaginous and with few branches which are elongate growing from a discoid base. The central strand is composed of filaments intricately entangled. [1]
The life-history is not fully confirmed. However carpospores and tetrasporangia have been recorded. [1]
Generally distributed around the European coast and the Atlantic coast of North America. [1]
The spelling of the specific name is in older references spelt without the first letter "h". However helminthoides is considered more correct. [1]

Atractophora hypnoides is a rare red alga (Rhodophyta) found in the British Isles, France and some Atlantic Islands and is the only species of the genus found in the British Isles. It is attached to the rock or other algae by a small basal disc and is much branched with downgrowing filaments which enclose the main branch or axis forming a cortex. Short filaments of limited growth radiate in whorls from the axis and frequently convert into hairs. The spreading filaments grow irregularly in a diffuse manner. Microscope examination is required for identification.
