Have you poked it or something I'm betting its a type of fungi if you poke it and it's not attached to the ground then it's leaves but again fungi I just don't know what type, also.have u lived where u live long I'm betting there will b more, and did it come up after the rain that would help others to id it

It is very fleshy and very weird, and finally is starting to die after a couple of weeks. Grew after a very rainy week or so in summer. Might be an old root under it from a cut down Box Elder Maple. Shaded.

I was waiting for you to google with the obvious search words, but since you didn't.....click on the link below. ;-)
