the base; spores oblong-fusiform, ferruginous-brown, .0005 
to .0006 in. long, .ooo16 broad. 
Pileus 1 to 2 in. broad; stem 1 to 2 in. long, 1 to 3 lines 
thick. 
Mixed woods or under or near coniferous trees in open 
places. New York, Peck. 
The original specimens, having been collected in a dry 
time, were not found viscid and were referred to the Sub- 
tomentosi, but later observations show that the pileus is 
viscid when moist, and the species is therefore transferred 
to the Viscipelles and placed near B. pzperatus from which 
it is easily separated by the colors of the pileus, the mild 
taste and the longer spores.

This species may easily be recognized by its peppery 
flavor. The pileus sometimes appears as if slightly tomen- 
tose, and both this and the preceding species recede from the 
character of the tribe by the slight viscidity of the pileus.
