  • All parts poisonous
  • Different people may react differently to it.
  • This fungus is sometimes mistaken for the edible field mushroom. It can be distinguished from the field mushroom by its unpleasant smell, its squarish stem and the yellow stain that often appears on the lower stem when bruised.
  • It occurs in lawns and gardens. Two thirds of reported cases of poisoning were in children under five years of age. In 86 per cent of these cases, the children ate mushrooms growing in their gardens at home.
