Found a Fairy Ring

I've been keeping my eye out for one of these for a while. I go for a walk around the perimeter of where I work most days and there is a very wide variety of fungi of all shapes and sizes. I spotted a good potential Fairy Ring once and thought I'd come back the next day and take a photo, but the grass had been cut the next day!

So finally spotted the best one I have seen so far:

Its not very clear, as the mushrooms can get a bit mixed up with the dead leaves on the ground, but they were definitely making a complete ring.

Here is the same photo but I have circled the mushrooms to highlight the ring:

Not as good as the one in the Wikipedia entry but a ring nevertheless.
