THE TUBE-BEARING FUNGI 



359 



The pileus is three to four 

 inches broad, dry, slightly 

 downy, convex, ochraceous- 

 brown, plane, often irregular 

 on the margin, sometimes 

 wavy, flesh white, and un- 

 changeable, taste mild or 

 sweet. 



The tube surface is nearly 

 plane and firmly set against 

 the stem, grayish, becoming 

 tinged with flesh color in age, 

 changing to a brown when 

 bruised; the mouths small 

 and nearly round. The stem 

 is covered with a fine mealy 

 substance, straight or flexu- 

 ous, sometimes reticulated 

 above. The spores are ob- 

 long, brownish flesh color, 

 12.5-15x4/*. 



The B. indecisus can be 

 readily told from B. felleus by its sweet taste and brownish spores. It is my 

 favorite of all the Boleti, indeed I think it equals the best of mushrooms. Its 

 favorite habitat is under beech trees in the open. It is widely distributed from 

 Massachusetts to the west. Found in July and August.

 Club-Footld Boletus. Edible. 



Clavipes means club-footed. Pileus fleshy, convex, glabrous, grayish-red or 

 chestnut-color. Flesh white, unchangeable. The tubes at first concave or nearly 

 plane, white and stuffed, then convex, slightly depressed around the stem, 

 ochraceous-yellow. Stem mostly obclavate, inversely club-shaped, and reticulate to 

 the base. The spores oblong- fusiform, 12-15x4-5//,. Peck. 51st Rep. 



The club-footed Boletus is very closely related to B. edulis. It differs, per- 

 haps, in a more uniform color of the cap, and in having tubes less depressed 

 around the stem, and less tinted with green when mature. The stem is more 

 club-shaped and more completely reticulated.
