Jania capillacea Harvey 1853: 84

Plants very delicate, forming dense clumps or cushions a few to about 10 mm tall, pinkish-red: holdfasts of small crusts or discs; axes cylindrical, sometimes curved inwards, tips pointed or sometimes rounded, branching dichotomous. Genicula inconspicuous. Intergenicula calcified, 300-600 µm long and 40-100 µm in diameter; fertile intergenicula larger than vegetative intergenicula, flask-shaped, with apical pore.

Collections, ecology and regional distribution

Epilithic or often epiphytic, in rock pools, lower eulittoral and sublittoral fringe. In our collections found only at De Hoop, Hluleka and Haga-Haga.

World distribution: Widespread in tropical and warm temperate regions (Guiry & Guiry 2014).

Type locality: Florida, USA (Yoshida 1998).

Note: We consider that this species may be a smaller form of J. adhaerens: further studies are required.
