The fungi involved produce compounds that reduce the amount of water that the soil can absorb, leading to drought conditions that cause the grass in the ring to brown and die.
Type 2 fairy ring fungi efficiently decay organic matter releasing nitrogen that promotes lush growth and leads to a dense green ring of grass. Finally, Type 3 fairy rings have rings of mushrooms that appear during wet periods, particularly in the fall.
What do I do with fairy rings in my lawn? Fairy rings in home lawns do not typically cause turf death and thus are primarily cosmetic problems. They often disappear naturally following a change in environmental conditions. Therefore, waiting for fairy rings to naturally disappear is often the simplest option for management. If you want to be more proactive in managing fairy rings, consider routine core aeration for your lawn.
Core aeration reduces the buildup of thatch which can harbor fairy ring fungi and make fairy ring development more likely. If you are having a problem with Type 2 fairy rings, also consider applying a nitrogen fertilizer to the rest of your lawn to green up the surrounding grass to match the color of the fairy rings. For Type 3 fairy rings, consider hand removing wearing gloves or raking up the mushrooms and disposing of them in your garbage; DO NOT eat the mushrooms as they may be poisonous.
Finally, DO NOT use fungicides for control, as products labeled for use in managing fairy rings are typically not effective in preventing fairy ring development or reducing the severity of symptoms.

Discard or kill a strip of sod 1 to 2 feet wide on each side of the zone of lush turf with a non-selective herbicide. Cultivate the area repeatedly to thoroughly mix the ring and nonring soil.
Eliminate dry spots by soaking the cultivated area with water. Reseed or install clean, ring-free sod. Some fungicides are available for suppression of fairy ring, however, they may be only temporary as the decaying material may still be present. Strategies 2 and 3 are strictly organic approaches.
