These tend to grow out of the decaying roots of a tree or large shrub that has been cut down in the past. Oftentimes, the stump has been removed or ground to a level below the lawn surface leaving the radiating roots close to the surface of the ground intact. It can take only a few, or sometime a lot of years before the mushrooms appear. Since the roots grow in a circular direction from the center of the stump, the mushrooms tend to grow in a circle. Hence, the term "fairy ring". Many people in subdivisions are surprised when these appear because they had no idea that the land developer took down the trees on their lot before construction began.

There are other theories as to why some mushrooms tend to grow in rings. For more information, here is a link to a Wiki article:

Answer 3

Fairy ring is a fungus disease. The mushrooms are the reproductive stage. Digging into the fairy ring reveals a white, fibrous growth (mycelium) throughout the soil. As the root-like mycelium spreads, the fairy ring enlarges from the outer edge. The mycelium can become so dense that water is unable to penetrate it. Consequently, the grass above the mycelium dies. There is no simple way to control them.

Answer 4

There are good mushrooms and poison mushrooms, there are no toadstools.But the answer you want is that the circles are marks of the fairies where they left their marks as a dog does.

Answer 5

There is a condition called "fairy ring" which sounds like what you describe Here in the south it is usually benign, in the north may cause problems. The fungus itself does not attack other plants, but robs the soil of oxygen. It can be controlled with almost any of the standard fungicides and even a few of the "organic" fungicides but must be used for two or three seasons.

Answer 7

To add to the other comments, the "ring" of toadstools is just the top of the overall plant--it is quite large underground, and can kill out the other plants.
