In addition to Fairy Rings, various other mushrooms may appear in lawns, but not injure the grass. However, they may be unsightly and cause people to worry that children or pets may eat them.

There is no easy control for lawn mushrooms which appear whenever there is a protracted rainy period. These mushrooms grow on organic matter (including thatch) and decaying wood. Where possible, the removal of buried wooden scraps and old stumps will reduce greatly their food source and the number of mushrooms in future years. Mushrooms that do appear can be raked up and destroyed, minimizing danger to children or pets.
