I remember that as a kid I was always enchanted by fairy ring mushrooms. Aside from the folklore, how did they manage to grow near one another in a perfect circle like that? Something mysterious was at work. Turns out, that something mysterious is just a common "root system", or mycelium, that the entire group sprouts from. I still find them enchanting, despite my soon approaching cross-over into my 30's. We need magic at every age... Fairy rings are your mycological whimsy.
This structure was knitted as part of my 52 Forms of Fungi project, through which I will knit a different type of fungi for every week of 2013.
