Black, thickly encrusting; skeleton as a reticulation of spongin fibers with a few spicules embedded in the ascending fibers. It can be confused with dark brown encrusting Amphimedon compressa. It has a reticulation of clear spongin fibers with a few spicules included. When touched, a subsuperficial pattern of vertical canals, wider than in A. compressa, is visible below the ectosome. |

Thickly encrusting, massive, flabellated or branching, from dark brown to purple to bright red, sometimes dark orange; all apparently seem the same species, with a reticulation of spongin fibers filled with oxea spicules. Dark specimens may be confused with black Amphimedon complanata. |

Amphimedon sp. gray-green branch-ridge |
3 |
Gray-green erect branches, single or in groups, sometimes flattened, looking like and irregular ridge; oscules usually aligned; surface conulose, especilly towards the tips. Consistency softly spongy, difficult to tear. Spicules oxea with rather blunt ends. It is probably an undescribed species, although being from South Florida, there may be old names available for it. |

Emerald or bluish green, crumbly masses with oscular mounds. Some specimens appear brownish. We consider A. erina (de Laubenfels, 1936) a junior synonym. |
