Scientific Description

Habit and structure. Thallus light to medium green, erect from a small holdfast and often flaccid, terete or compressed, mostly 5–15 cm high and 0.5–2 cm broad, usually with frequent, proliferous branches but sometimes almost simple. Cells usually arranged in longitudinal rows, often partly disrupted above, and to some extent in transverse rows, typically angular and four sided in upper thallus, 10–14(–16) µm long and 8–12(–14) µm broad, more rounded and larger in the stipe (to 25 µm long); chloroplast occupying most of the cell, with a single, relatively large pyrenoid occupying 20–60% of the cell width.

Reproduction. Generations isomorphic, gametophytes dioecious, anisogamous.

Distribution. Widely distributed in temperate seas.
