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 un- 
pleasant 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. The species is apparently allied 
to &. trzdentinus Bres., from which it differs in the color 
of its flesh, veil, tubes and spores. The color of the latter 
is darker than in any other species of this tribe known to 
me. It approaches mummy-brown but has a slight purplish 
tint.
