>>27705266It's a Fairy Ring, though. Judging by the design, and what Fairy Rings are...
I imagine the face and feet/roots are the actual Pokemon, and the mushrooms are like... 'hair' to it. It looks like the bulk would be underground traditionally, while the mushrooms stick up. It'll probably even look like 'just a mushroom' until you get close, then pop out of the ground at you.
So... the evolution could have the body get larger with more 'roots', and a large circular formation of mushrooms could grow off of it to stick out of the ground in a ring shape.
