The cells of this species have a distinct club-like appearance and may grow to as much as two inches in length. It tends to grow in a creep-like fashion along the substrate with occasional offshoots becoming erect up to two inches tall. Smaller than V. macrophysa and not forming massive mats, it consists of bubblelike, branched filaments composed of relatively large, cylindrical cells up to two inches long but only 0.2 inch wide. Mainly found attached to hard substrate in cracks, crevices or other protected areas (from predators).
