Their smooth gray bark can most easily identify beech trees. You can also identify them by their rounded leaves that end in a pointed tip. The leaves will also show leaf grains that run parallel to themselves. Be careful, though; double-check yourself to make sure you’re not looking at a false beech tree.   Once beech has been dried and seasoned, the color of the wood will have overtones of pink or light orange in them. If you are seasoning beech wood and it starts to turn black, green, or blue, you may have a mold infection.
