. Colonies up to 1.3 cm high, erect, monosiphonic or weakly polysiphonic basally, arising from a thin, creeping hydrorhiza. Hydrocaulus smooth, with perhaps a few corrugations or wrinkles. Internodes long, smooth, with a proximal node, sometimes indistinct. Ramifications irregular, scarce, in one plane, sympodial, with a zig-zag pattern in young branches. Hydrothecae at end of normally long pedicels. Pedicels alternatively left and right, on poorly defined distal apophyses of internodes, with a few basal rings or wrinkles and slightly widening towards distal end. Hydrothecae radially symmetrical, campanulate, with thin and smooth perisarc. Operculum short, formed by 9–10 rounded facets not clearly demarcated from hydrotheca, sometimes distally truncated. Diaphragm basal, very thin. A ring of desmocytes is occasionally present at a short distance over the diaphragm.
