The plateau is composed mostly of two Miocene carbonate units, the Isla de Mona Dolomite overlain by Lirio Limestone. These two units consist primarily of back-reef sands with a reefal sequence present in the Lirio Limestone to the southwest. The Lirio Limestone is heavily karstified with numerous sinkholes in the central part of the island resembling present-day cenotes of the Yucatan peninsula. Numerous large cave openings are ...

Littler and Littler (1994, 1995, 1998) reported the presence of two disease conditions, coralline lethal orange disease (CLOD), and an undescribed fungal pathogen on the coralline alga Porolithon onkoides. Presence of a coralline algal syndrome characterized by a white band front has recently been recognized in several localities in the Caribbean (Weil 2004). Our observations indicate that this condition is common on Neogoniolithon accretum at 17 to 20 m in southwestern Puerto Rico. A preliminary survey in one deep-reef locality indicated that approximately 70% of the N. accretum colonies were infected and some of these colonies were nearly 80% dead. The condition bears a superficial appearance to coral white band disease and is hence referred to as coralline white band syndrome. Affected N. accretum show a well-defined white band over algal tissue that occurs as an e ...

The new species produces strap-shaped thalli supported above the substrata by abundant peg-like stipes. The lobed branches are frequently anastomosed with colonies measuring to 4.0 cm broad with individual axes measuring to 7.0 mm across. Algae possess up to five layers of medullary cells with frequent open spaces in the medulla. Tetrasporangia, measure to 19 × 25 μm, and are borne in sori limited to ventral surfaces. Gametophytes are monoecious and hemispherical carposporophytes are produced dorsally, measuring to 900 μm in diameter and 600 μm high.
