Sorry for the bad photo, my dog was not cooperating when I was in the brush getting my photo.
I have never come across a puffball that is as green as this one. Not sure if others have seen this?
This would be one hell of an amanita! This guy is 12 inch across. It turned more yellow over time, I think this is just a vibrant process of spores being formed in the tissue. It was very interesting to watch.
