Well, it seems hard as a rock. I tried yanking each from where they are growing, no way, it would have to be cut.
I cut a little off the piece that was in the bottom picture of my first post - when it cut it had that squeaky quality you get with regular grocery store mushrooms, but it was pretty firm. I had a rather small knife and there was no way I could tear the very last bit - I had to cut it all.
Inside it is a dark brown with rings, it rather looks like wood. It smells like a cross between a mushroom and wood.
I was looking at my book and if it's a puffball, maybe it's a tough puffball - or Mycenastrum Corium.
I dunno about the polypores but it doesn't seem like your guess. Sorry I didn't describe the touch and cut of it at first, I'm still learning this stuff.
I was hoping, most of all, that these threads might help me find a group of mushroom foragers.
