Material examined. 51217#1 , several stems up to 30 mm high, on bryozoan, and a few stem fragments up to 40 mm high, no coppiniae. Description. Colonies with both stolonal hydrothecae and polysiphonic stems, at least 40 mm high. Stems little branched, straight. Hydrothecae irregularly arranged all around stem, practically without pedicel (Fig. 3F); frequently completely sessile, inserted directly into the branch. Hydrothecae cylindrical, basally narrowing into a short pedicel (Fig. 3G). Measurements (in µm). Hydrotheca : diameter at aperture 190–200; length up to diaphragm 600–740.

According to Schuchert (2001), L . dumosa has a complicated, not fully resolved, taxonomic history. He found distinct differences in relation to the size and shape of the hydrothecae, and the presence or absence of hydrothecal pedicel, even among colonies from the same locality.
