Tricholoma inamoenum
Tricholoma inamoenum is a mushroom of the agaric genus Tricholoma found through the Northern Hemisphere, particularly under conifers. It is poisonous, and is characterized by an unpleasant odor resembling coal gas or tar. • Analysis of the volatile compounds emanating from fresh sporocarps using solid phase microextraction showed the odor compounds responsible for the coal tar odor of this mushroom are 1-octen-3-ol and indole.
Seattle's Tricholoma platyphyllum may be the same species. A similar species is Tricholoma sulphureum, which is found under both conifers and hardwoods.
