Areas dominated by microbes that form a soft or hard structure visible to the eye. Soft structures are usually formed through accumulations of conspecifics and other microbes into a matrix that appears as strands, a thin film, or a thicker mat. Hard structures generally form through secretions and entrapment of minerals and sediments.
