Slide 48.
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).
