I saw one just a couple days ago. They are usually prevalent after a heavy rain. And we’ve had tons.....................
I’ve had them in my lawn a time or two, in shadier parts of the lawn. They’re pretty magical when you just stumble on to seeing one for the first time.
Kind of like seeing ‘Foxfire’ in the woods at night for the first time - decaying matter (fungus) that glows orange or green at night.
However, I would advise against frying up a Fairy Ring for supper! ;)
