Old Walnut Stump Fungus: Nature's Recycling

2-ft diameter walnut stump covered in mold, smelling like rotting carcass after rain. Kids nearby.

Reality

Wood-rotting fungus—nature's way of decomposing the stump. Smell unavoidable. Scraping only brings it back. No harm to children even if ingested. Let it run its course; patience required.
