Size (Zooecium): Length 450-550 µ; breadth 225-250 µ.

Zoarium light greenish in hue, branching irregular and hence the zoarium forms a tangled mass. Rounded stolons large and semi-transparent. Zooecia arranged bilaterally on either side of the stolon, but may occur in an irregular crowded fashion. Elongated ovoid zooecia show variations in size, the place of attachment of the zooecia to the stolon, rounded and narrow, the distal portion being blunt and squarish in shape. Tentacles seem to be eight in number. A gizzard present.
