Diagnosis | Colonies composed of stolonal hydrorhiza giving rise to monosiphonic stems up to 2.5 cm high. Stems unbranched or scarcely branched; branches without anastomoses. Hydrothecate internodes long and thin, usually longer than hydrothecal length. Hydrotheca placed on distal third or quarter of internode. Hydrothecae alternately arranged in one plane, large and tubular. Adcauline hydrothecal wall adnate for approximately one-third of its length. Free part of adcauline hydrothecal wall straight or slightly convex. Abcauline hydrothecal wall straight or slightly concave. Cusps of hydrothecal aperture sharp and separated by deep embayments. Occasionally with hydrothecal renovations. Gonothecae ovoid, with short distal neck; walls smooth or slightly wavy, with indistinct striae. |
