A beautiful species, with smooth purph'sh-red cap, bright yellow 

 tubes, and smooth, red, or yellow stem. When broken both flesh 

 and tubes change to blue. This plant has been reported from 

 only a few localities. Beardslee reported it very common in the 

 mountains of West Virginia. Edible. 



Boletus castaneus Bull. 



Rare in sandy soil in open woods. 



This species has a hollow stem and dries easily. The cap is 

 reddish brown, the flesh white and unchangeable, and the free 

 tubes are at first white then yellowish. It is widely distributed 

 and usually common. Edible. 



Boletus chromapes Frost. 



Very abundant in open woods throughout the valley and on 

 the adjoining slopes. 



A very attractive species, and one easily recognized by its 

 stem, which is bright yellow near the base and finely scabrous 

 over its entire surface. The cap is pale red and the tubes and 

 most of the stem white. Edible. 



Boletus chrysenteron Fries. 



Found a few times on roadside banks. 



This species is widely distributed and usually common. The 

 cap and stem are usually red and the tubes yellow and large. 

 It dries easily, being spongy-tomentose in texture. The surface 

 of the cap is soft, finely floccose, and often cracked. Edible. 

 Boletus cyanescens Bull. 



Rather common in open woods, at times solitary, but usually 

 gregarious. 



A common and widely distributed plant easily known by the 

 deep blue color which its flesh and tubes assume when wounded. 

 The cap is pale tan and floccose-tomentose, the tubes and hollow 

 stem white or pallid. It dries very readily. 



Boletus eximius Peck. 



Several times collected in thin woods and along roadsides. 



The stem of this species is very characteristic, being lilac-gray 

 and furfuraceous, while the cap and tubes are chocolate-brown. 

 This species has been rarely reported, but I have it from New
