I'm relatively new to mushroom foraging, found this guy while mowing today here in Clemson SC. It was in the grass near a lobolly pine. Has some worn down worts or scales on it. There was no stem, it is pretty firm on the outside and very firm on the inside. Looks like a delicious layered chocolate cake.. Smells earthy but no overwhelming smell. Haven't yet been able to find any pictures of a truffle or and earth ball like this. Any help would be greatly appreciated!
I had already cut it in half before taking these pictures
