No, marshes are seperate from bogs and fens, forming at the edges of bodies of water, rivers, or in tidal areas and subject to periodic inundation. A bog or fen is an independent pool, fed by precipitation or surface and groundwater respectively, which forms a bed of peat.
I don't think mire is a classification in this sytem.
Does that mean that a marsh can be a fen or a mire depending on acidity?
