|If the mushrooms are random or scattered rather than in a circle, they are probably growing because there's something underground that's decomposing. Usually an old tree stump, tree roots, or even leftover wood from construction are causes for mushrooms growing on the soil surface. A thick layer of decomposing thatch can also encourage mushroom growth. You can rake up the mushrooms before they mature and release spores (that will produce more mushrooms) and dispose of the mushrooms in the trash rather than tossing them into your compost bin. You can dethatch this fall if necessary. All lawns develop thatch but if the layer of thatch is more than an inch thick you'll want to power rake the lawn to remove the thatch. Good luck with your lawn.
