Original Description

Test free, tubular, branching, flexible; forming tangled weed-like tufts of indefinite size. Texture chitin-arenaceous, slightly rough externally; colour brown. Monotypic.

When spread out on a white surface the mass is seen to be composed of branching tubes, varying in diameter from 1/200 to 1/80 of an inch (0.53 to 0.32 millim.). What their original length may have been it is impossible to say, but it is seldom that pieces can be separated of more than an inch or an inch and a half long. There is no evidence that it has grown attached to any foreign body, though it is quite possible that it may have done so. The branching does not take place on any definite plan. Entangled amongst the branches are often fragments of Polyzoa and other similar organisms.

Size:
Diameter 1/200 to 1/80 inch (0.53 to 0.32 mm.); length up to 1 or 1.5 inch.
