THE TUBE-BEARING FUNGI 



367 



I found some beautiful specimens in a mixed woods on the Edinger hillside, 

 near Chillicothe. I located them here, but observing that this species was not 

 common I sent some to Prof. Atkinson, who placed them under this species. 

 August. 



Boletus radiants. Pers. 



The pileus is convex, dry, subtomentose, olivaceous-cinereus, becoming pale- 

 yellowish, the margin thin, involute. Flesh pale-yellow, taste bitterish. 



The tubes are adnate, their mouths large, unequal ; lemon-yellow. 



'The stem is two to three inches long, even, tapering downward and radiating, 

 flocculose with a reddish bloom, pale-yellow, becoming naked and dark with a 

 touch. 



The spores are fusiform, olive, 10-12.5X5/X. Peck, Boleti of the U. S. 



I found these specimens in the same locality with the B. strisepes. 



The olivaceous cap with its peculiar involute margin and its radiating stem 

 will greatly assist in its determination. August.
