Getting rid of mushrooms in your lawn may be a bigger job than you really want to mess with. The top of the mushroom contains tons of tiny little seeds that spead the mushrooms in your yard. You can dig up the mushroom and make sure you get all the stem, but in the mean time you could be spreading the seads out of the dirt and mushroom! You may call a lawn service and they could get you mushroom free easier and faster! Good luck to a mushroom free lawn!
