This is a rare and showy species 

 which inhabits the cold northern swamps of the country. It probably 

 extends into Canada. When cut, the flesh emits a strong, unpleasant 

 odor. Wounds of the flesh made by insects or other small animals have 

 a bright-yellow color! When young, the tomentose veil covers the 

 whole plant, but it soon parts into scales on the pileus and partly or 

 wholly disappears from the stem. Peck, Boleti of the U.S.
