Usually there are some edible puffballs that emerge this time of year. They are easy to identify, and don't seem to be as prone to freeze damage as some mushrooms. I like the smaller ones. They smell like Parmesan cheese. An edible puffball can be identified by cutting it in half. If it is white inside it is purported to be edible. If it is gray or brown, not so much. I did not pick this one, so I don't know.
