This species may easily be recognized by its peppery flavor. The 

 pileus sometimes appears as if slightly tomentose, and both this and the 

 preceding species recede from the character of the tribe by the slight 

 viscidity of the pileus. This is sometimes cracked into areas and some- 

 times the margin is very obtuse by the elongation of the tubes. Peck,

This fungus is reckoned poisonous by Stevenson. Massee gives its 

 taste as very hot. The taste of the American plant is peppery but not

 by the writer and his friends with enjoyment and without any discom- 

 fort.

 arating from the stem with the expansion of the pileus, reddish, the 

 mouths minute, stuffed at first, pinkish, then brownish-yellow, changing
