Hello and thank you @bambuka! I find Chaga in the same forest as well (see images), but I have never seen Chaga with the same red/ochre color and fan shape. Have you? Whenever I find Chaga it is in lumpy masses on tree wounds but never like this before. It is my favorite so far because I cannot figure out exactly what it is! Some sort of brown-rot fungi? Looks like a woodpecker got to it before it fell to the ground.
