The sulphur tuft mushroom clump, which is growing on a cut down sycamore tree by the path in the woodland garden mushroom is poisonous, so don't be tempted to touch, let alone eat! It contains poisons that can cause liver damage, symptoms are nausea, vomiting, diarrhea and emesis. The clump is decaying a bit and the first frosts will see it off.
