Not really. Mushrooms usually emerge during periods of excessive moisture. They will most often grow in a cluster, accompanied by darker grass in the shape of a crescent moon. Lawn care professionals call this “Fairy Ring”. You will often find more than one of these crescent moons lined with mushrooms in an average lawn. The mushrooms occur as a result of decomposing organic matter, such as a tree stump or branch below the surface of the lawn. A stray piece of wood left behind during the construction of the home might also be the cause. Thus, fairy ring tends to be more prevalent in newer suburbs. While removing the dead piece of wood might seem to be the obvious solution to this problem, finding it is another story. You may dig up your lawn only to find a giant tree stump. You may dig up your lawn and find nothing at all if you aren’t digging in the right spot or if you don’t dig deep enough. Fairy ring is usually short lived. The best thing you can do is remove the mushrooms by hand if they bother you that much, and hope that conditions change sooner rather than later. The problem will reoccur whenever it gets wet enough. If you’ve heard that sulfur will kill the mushrooms and the fungi that cause them, keep in mind that a direct application of sulfur will also kill your grass.
