Branches wider in the lower portion, about 3-3.5 mm in breadth, becoming characteristically and abruptly narrower in the upper portion of the thalli, 0.1-2 mm in breadth. Angles between the branches wide, hence the spreading habit. Margins of the branches entire, apices bifid and acute. Thallus composed of superficial layers enclosing in between a middle layer; cells of the former small, more or less quadrate, richly provided with chromatophores. Cells of the middle layer large, more or less rectangular.
