From the Wiltshire Times :
A large fairy circle has appeared in the lawn of Tom and Sue Gaylard's home...
"It amazed me. I had never heard of it or seen anything like it before and I couldn't believe it."
The perfect ring of mushrooms, know as a fairy or pixie circle, first appeared about three years ago and has re-appeared annually, each time getting bigger.
"We don't believe in fairies of course but it is known as that. We didn't really pay much attention to it but then our daughter-in-law saw it and ran out to make a wish in it."
In times gone past the rings, some of which are hundreds of years old, defied explanation spawning a host of legends in countries around the world to explain their presence.
In English folklore the rings were said to be caused by fairies dancing in a circle, wearing down the grass beneath their feet. Toads would then sit on the worn down areas, poisoning it and allowing the fungus to grow - hence the name toadstool.
The rings are in fact naturally occurring circles of fungi that can grow up to 10 metres in diameter. They are caused by fungi under the ground casting out spores in a circular pattern resulting in the distinctive ring.
In some cases the fungi remain underground and the ring is marked by discoloured patches of grass.Now You Know.
