and smooth or nearly so and variable in color. The prevailing 

 colors are gray and brown variously blended and often inter- 

 mingled w^ith 3^ellow. It may be brown when young fading to 

 grayish brown or yellowish brown when mature. The flesh is 

 yellow but this also varies in depth of hue. The tubes some- 

 times form a plane surface beneath the cap but sometimes 

 those around the stem are a little shorter than the rest thereby 

 forming a depression in the surface. They have a clear yellow 

 color which becomes darker with age. They do not assume 

 blue tints where bruised or wounded. The stem is usually of 

 equal thickness throughout. It is solid and reticulated with a 

 network of ridges from top to bottom. Its color both exter- 

 nally and internally is yellow. 



The cap is 2-5 inches broad; the stem 2-4 inches long and 

 4 to 6 lines thick. This boletus grows in thin woods or in open 

 places. It is sometimes found on earth banks by roadsides. 

 It appears during July and August. It is clean, sound and well 



flavored.
