Description
Size: Height 10-15 cm.

Color: Brownish, olive-green

Basal portion stoloniferous, creeping on the surface of the substratum, giving rise to dichotomously branched upper portion. Branches elongated, sometimes spirally twisted, distantly situated, broader at the base, becoming narrower upwards, apices narrow, acute, margins of the branches entire or more or less dentate. Thallus in the upper portion, composed of superficial layers enclosing a single layer of cells. In the lower portion it is built up of superficial layers enclosing two or more layered middle tissue. Cells of the superficial layers thick-walled, isodiameteric, 17-31 µ long and 16-29 µ broad; richly provided with chromatophores. Cells of the middle layers large, more or less regularly arranged in the thicker portions of the thallus, cells 32-128 µ long and 32-103 µ broad, poor in contents.

Reproductive bodies scattered on the surface of the branches. Antheridia forming sori, numerous each cylindrical, 45-55 µ long and 8-10 µ broad. Oogonia also in sori, clavate in form and 90-95 µ long and 20-24 µ broad. Hairs occurring among oogonia. Tetrasporangia, usually solitary, sometimes occurring in groups of 2-3, oval in shape, containing several spores formed by parallel and longitudinal divisions.
