I found these shelf mushrooms growing on a tree. Much to my surprise they broke of easily and I could even break it in half, I did not need to cut them. I am not sure if they were just old and decaying or they were just softer flesh. They were very black on the bottom Mixed forest.

This is a very old specimen, probably from last year. The photo of the underside is not well focused but I would guess the black color is decay from another fungus or from multiple fungi.

I am new at this and have much to learn. I do see how close it is to Piptoporus betulinus. Could you explain, so I will understand, why they were black on the bottom? Is that due to the color of the spores? Or something else? Thanks in advance for sharing your knowledge.
