Description.
Colonies encrusting (
Fig. 6
A). Zooids more or less oval, with transparent frontal membrane underlain by narrow beaded cryptocyst. Gymnocyst smooth-textured, narrow distally and laterally, more extensive proximally, sloping to zooid margins (
Fig. 6
B). Recently formed zooids with small orificial spines. Aviculariumkenozooid complex similar in size to autozooids, kenozooidal opesia large, covered by membrane, the proximal avicularium with figure-eight shaped foramen, tiny acute pivots and spatulate rostrum with a broad palatal shelf (
Fig. 6
E). Ooecium prominent, with tubercular surface calcification, small relative to zooid size (
Fig. 6
C, D).
Remarks.
Living colonies have dark-green polypides with pale orange tentacles and orange embryos.
Distribution.
Tropical western Atlantic. Cape Hatteras to Florida, Gulf of
