The elementary and microscopic constituent of coal. There are a number of different types. Alginite is formed from algal remains; collinite from cell infillings; cutinite from plant cuticles; and fusinite from woody material. Micrinite is opaque, granular, and has no cell structure. Resinite consists of small ellipsoids or spindles of resin, a cell-infilling material; sclerotinite of variously sized round or oval bodies of irregular structure, which may have been fungi or spores; sporinite of spore exines, usually flattened parallel to stratification; and telinite from cell-wall material.
