Common names

(as Chordaria flagelliformis (O.F.Müller) C.Agardh)
English: Slimy Whip Weed (Bunker & al. 2010).

German: Geisseltang (Braune 2008).

Japanese: Naga-matsumo (Tokida 1954).

Thallus string-like, with divaricated branches, slippery, solid, dark-brown to black, 10-30 cm high. Branching irregular, alternate from all sides. Branches cylindrical, or slightly compressed, to 3 mm wide, slightly tapering towards the base. Branch apices blunt. Medulla composed of longitudinal filaments of long cylindrical cells to 50-600 µm decreasing towards periphery to 16-18 µm. A layer of assimilative unbranched filaments (of 4-9 cell rows) develop from the peripherical cells. Unilocular sporangia oval, 20-23 x 60-108 µm, develop at the base of the assimilative filaments.

Growing on stony bottom, in low intertidal to subtidal, in calm shores and exposed to wave action.
