Description: This species is an encrusting colony composed of calcified tubes, all about the same size, and fused together. It grows out into fanlike lobes. The apertures are round and have no operculum. It has no avicularia nor spines. The ooeciostome is on the end of the ovicell, separate from a peristome, and has a round aperture about 60-80 microns in diameter. The peristomes are not arranged in bundles nor in rows (though the above specimen appears to have roughly diagonal rows).
