This is a marine species.
Plants prostrate and mat-forming, attached by multicellular rhizoids with or without digitate tips; rhizoids 7-9 µm diam., issued from periaxial cells or replacing a whorl-branch opposite to a whorl-branch or indeterminate lateral; median cells of indeterminate axes 15-23 µm diam., 42-67 µm long; indeterminate axes distichously branched from each axial cell, each pair consisting of two whorl-branches or less frequently, one determinate and one indeterminate lateral (determinate not suppressed); indeterminate apices crowded with partially developed whorl-branches on non-elongated axial cells; whorl-branches 5-8 cells from base to tip, issued at angles of 65-90 from upper portions of axial cells, later ascending dorsally at angles of 30-45 from prostrate indeterminate axes, incurved near apices, but when branched becoming slightly to markedly recurved at maturity; whorl-branches simple or unilaterally branched 1-2 times, periaxial cells 10-13 µm diam., indistinguishable in length and shape from cells distal to them, branches gradually tapering to 5-8 µm diam. at the tips; gland cells dividing laterally from subapical whorl-branch cells, at maturity completely covering the adaxial surface of the second or third cell from the base of whorl-branch, infrequently on the periaxial or fourth proximal cells, 0-1 per whorl-branch, suppressing a branchlet or rarely displacing it to the abaxial position, and never found on branchlets; reproduction unknown.
