Hah. On the roots of Laminaria digitata, on Flustrae, corallines 
and old shells, common. 
This frequently covers a space about an inch square, the branches 
diverging and creeping along the surface or the entangled roots of 
sea-weed, to which they are attached by simple tubulous root-like 
fibres pullulating from the plane inferior surface. The branches are 
rather broad, dichotomous, of an earthy brown colour, brittle when 
dry. Within the cells I have occasionally seen one, or sometimes 
two, nearly globular orange-coloured ova. 
3. C. reptans, creeping , dichotomous ; cells alternate with an 
oblique aperture armed with short spines at the top. — Ellis.

Similar to the preceding in form and mode of growth, but its spread- 
ing tufts cover in general a larger space, and are more densely matted.
