Structure: Ranges from a flat to hemispherical shape, potentially surpassing a diameter of 5 meters; exhibits a phaceloid to flabello-meandroid formation with valleys that irregularly divide. Fusion of multiple colonies with varied colors and textures in the polyp mantle can create a unified composite stand. Septa: Thickness gradually diminishes from the wall to the columella, featuring tall, sharp teeth. Polyps: Retracted state reveals thick and fleshy characteristics. Mantles can be either smooth or rough. Color: Displays uniform hues or incorporates two or more concentric colors around mouths or valley walls; corallites within the same colony share consistent coloration.
