woodlands throughout most of Europe and the United States, 

 sometimes occurring in great quantity in one spot. Its odor is 

 similar to that of peach kernels, and in some specimens it is 

 strong and unpleasant, although at times it may be scarcely 

 noticeable. This unpleasant odor and the very slimy character 

 of the surface render the plant unattractive and one would hardly 

 collect it for food. It is known to be definitely poisonous to 

 a certain extent and should always be avoided by mycophagists.
