color when bruised and whether the taste is pleasant or otherwise. When I first 

 began to study the Boleti there were but few species that were thought to be edible, 

 but the ban has been removed from very many, even from the most wicked, 

 Boletus Satanus. 



Boletus scabcr. Fr. 

 The Rough-Stem med Boletus. Edible. 



The pileus is from 

 two to five inches in 

 diameter, rounded con- 

 vex, smooth, viscid 

 when moist, minutely 

 woolly, velvety or 

 scaly, color from near- 

 ly white " to almost 

 black, the flesh white. 



The tubes are free 

 from the stem, white, 

 long, mouths minute 

 and round. 



The stem is solid, 

 tapering slightly up- 

 ward, long, dingy- 

 white ; roughened with 

 blackish-brown or red- 

 dish dots or scales, this 

 being the most pro- 

 nounced characteristic 

 by which to distinguish 

 the species ; three to 

 five inches long. The 

 spores are oblong fusi- 

 form and brown. 



Prof. Peck has de- 

 scribed a number of 

 varieties under this 

 species, most of which 

 depend on the color of the cap. All are edible and good. 



This is a common plant, usually found in woods and shady waste places, from 

 June to October. Photographed by Prof. H. C. Beardslee.
