This was growing on a large maple tree just outside of Richmond Indiana. The surface was soft and spongy with an underlying hardness. Texture was spongy but also had a grainy feel to it-reminded me of sand. The larger one was roughly 10 inches across with an overall height of roughly 4 inches. There did seem to be another smaller one located on the underside. There was another one located several feet about the first one to the side-could not determine if they were the same due to the height. No sample was taken.
