Description

This small alga is no more than 8 cm long. It appears as a tuft of irregularly branched erect axes. The branches show 10 periaxial cells forming a collar around a central axis without cortication. The pericentral cells are all of the same length. Rhizoids are attached to the lower periaxial cells. [1]

Reproduction

Tetraspores have been recorded in the final branches.

Distribution

Recorded from the south coast of England, Ireland and the Channel Islands. Also recorded from north-west France. [1] [2] Occurs southwards to Morocco. [3]
