 thick, glabrous, subshining, often pitted, pitted or corrugated, brownish- 

 red or dull-lilac, sometimes fading to yellowish on the margin. Flesh 

 white, unchangeable. Tubes at first nearly plane, adnate, white and 

 stuffed, then convex, depressed around the stem, ochraceous-yeliow or 

 brownish-yellow and sometimes separating from the stem by the expan- 

 sion of the pileus. Stem equal or slightly tapering upward, reticulated 

 either wholly or in the upper part only, colored like the pileus or a 

 little paler, sometimes slightly furfuraceous. Spores subfusiform, brown- 

 ish-ochraceous, 12-15x5-6^.

One of the handsomest of Boleti. It varies greatly in size and 

 color, but traces of purple or lilac are always detectable. The reticu- 

 lations upon the stem are often obscure, especially in young specimens. 



It is pleasant when raw, and quite equal to any Boletus when cooked.
