Tricholoma sulphureum and its somewhat close look-alike, Tricholoma inamoenum could be confused with the vaguely similar and edible Tricholoma flavovirens until one gets a good smell. Both Tricholoma sulphureum and Tricholoma inamoenum are characterized by a foul smell that should discourage anyone from eating them. The repulsive combination of rotten eggs and coal tar gas makes it hard for me to even stay around long enough for a good picture. In addition to causing gastrointestinal distress, Tricholoma sulphureum contains a hemolysin that could attack red blood cells. However the hemolysin is either destroyed on cooking or by the digestive system. Indeed, many good edible species contain a hemolysin that is destroyed on cooking. These include Clitocybe or Lepista nuda, Amanita rubescens, Flammulina velutipes (the Enoki mushroom), and Volvariella volvacea (the Paddy Straw mushroom).
