MUSHROOMS, EDIBLE AND OTHERWISE 



turned under the margin adhering- to the tubes. It is a large and imposing plant 

 found in sandy soil and especially among the pines. I found it in J. Thwing 

 Brooke's woods, Salem, Ohio. August to October. 



Boletus gracilis. Pk. 



The Slender-Stemmed Boletus. Edible. 



Gracilis means slender, referring 

 to the stem. 



The pileus is one to two inches 

 broad, convex, smooth or minutely 

 tomentose, the epidermis frequent- 

 ly cracked as in the illustration ; 

 ochraceous-brown, tawny, or red- 

 dish brown ; flesh white. 



The tube surface is convex to 

 plane, depressed around the stem, 

 nearly free, whitish, becoming 

 flesh-colored. 



The stem is long and slender, 

 equal or slightly tapering upward 

 usually curved ; pruinose or mealy. 

 The spores are subferruginous, 

 .0005 to .0007 inch long, .0002 to 

 .00025 inch broad. 



This is quite a pretty plant, but at first sight it will not be taken for a 

 Boletus. They are not plentiful in our woods. I find them only occasionally and 

 then sparsely. They are found in July and August, the months for the Boleti. 

 They grow in leaf mold in mixed woods, especially among beech timber.

Boletus stricepes. Seer. 



Striaepes means striate stem. 



The pileus is convex or plane, soft, silky, olivaceous, the cuticle rust-color 

 within, flesh white, yellow next the tubes, sparingly changing to blue. 



The tubes are adnate, greenish, their mouths minute, angular, yellow. 



The stem is firm, curved, marked with brownish-black striations, yellow, and 

 brownish-rufescent at the base. 



The spores are 10-13X4./A. Peck, Boleti of the U. S.
