Thalli epilithic, polysiphonous, ecorticate, attached by
unicellular rhizoids cut off from pericentral cells, terminating
multicellular hapteron; 3-7 cm tall, dark brownish

µm broad in middle to upper portion; branches alternately
distichous with subacute apices, borne at intervals
of two segments, slightly incurved in upper portion,
