what you want to know about it. My photo is old and doesn’t show any details, but the fruit body was developed on a tree that already had fallen down.

Its life cycle starts with an infection in a small wound on the tree, that creates the sterile conks (chaga). They act like cancer and aim to weaken the tree and eventually kill it, then it’s time for the fertile stage, the thin pore layer under the bark.

obviously I’ve never seen Chaga fruit bodies. I don’t understand what I’m seeing here. Can you explain? I’m Chaga collector and would love to understand this.

Nice photo

Excellent – proof that the fruiting body DOES exist!
It ties in with the thread on Observation 8136
