During the transformation from leaves and twigs to hard, shiny black coal, we change the name, first to peat, and then to coal of different types, lignite, then bituminous, then anthracite. You'll generally find that as time, heat, and pressure change the organic materials, they also change the rest of the sediment around the coal.
