Description:
Hidden cup corals form small, encrusting groups of 1/2 inch polyps often appearing to be disconnected.  Algae, sponges and other organisms overgrow colonies, making polyps somewhat inconspicuous.  This species is often found in dark recesses.  Color ranges from red-brown to yellow-brown.  Typical corallite diameter for this species is 1/2 inch.

Habitat:
Phyllangia americana occurs on rock ledges as well as on the bases of dead Oculina reefs. It can occur at depths from 3 - 10 feet to more than 250 feet, and can withstand moderate wave exposure in shallow locations.  It is most commonly found in water less than 60 feet deep

Range:
P. americana occurs along the Florida coast and throughout the West Indies. It is typically found on nearshore reefs off coastal Florida, and around inlet areas of the Indian River Lagoon.
