Description Shape and size: Thinly encrusting species (2-5 mm thick),in
patches from five to a few hundred cm2. Surface: Smooth. Oscules (1-2 mm diameter) on top of low volcano-shaped mounds (1-2 mm of height). Consistency: Crumbly and brittle. Colour: In live, dark purple, inside and out. Cream to white in alcohol. Ectosomal skeleton: No organization, spicules strewn tangentially. Choanosomal skeleton: Isotropic unispicular to paucispicular reticulation forming polygonal meshes (100-320 ¼m in diameter), and paucispicular primaries (2-3 spicules across) 200-300 ¼m apart. Filamentous cyanobacteria densely packed around the skeleton. Spicules: Fusiform to slightly hastate stout oxeas in one size class (230-320 x 8-15 ¼m), with pointed ends. Sigmas, c-shaped (10-26 x <1 ¼m).
Ecology: The species was found growing in small patches on mangrove roots, empty shells, or coral rubble, and occasionally profusely overgrowing live corals. Also found on shallow reefs (0-15 m deep) growing over coral and bare rock substrates.
