						30mm long, polysiphonic over almost its entire length. Main stem giving rise to three branches on the same side and another branch on the opposite side; branching approximately in
one plane. Hydrothecae alternately arranged in one plane, forming two longitudinal rows. Hydrothecae only slightly immersed into the branches, strongly curved outwards. Adcauline hydrothecal wall free for approximately half of its length. Free adcauline wall straight or slightly convex. Abcauline hydrothecal wall concave. Aperture circular; rim even and usually provided with numerous short renovations, tilted downwards, forming an acute angle with long axis of branch. Hydrotheca lacking mushroom-shaped diaphragm.
