I went yesterday and scored some ash. A small amount was on the ground for some time. I took what I thought to be not rotten. The rest of it was still standing with no bark, I cut down. Can someone please tell me if I should burn this in my stove or if it's so far gone I should throw it in the firepit next summer. The first pic, after split, it was almost brittle and crumbling apart. The other is some in my wheelbarrow and one of the pieces has something white on it. Any help would be greatly appreciated. I'm not worried about the other ash I have as the bark is just starting to fall off and it split nicely.
