Thin woods. Albany and Saratoga counties. July to October. 



This species resembles B. Americanus in color, but differs from it 

 in its thicker pileus, stouter stem and differently colored spores. 

 These have nearly the same color as those of B. Ravenelii. In its 

 more robust habit it approaches B. granulatus. The minute hairy 

 squamules of the pileus are a peculiar feature, but they are not 

 always present. The glandular dots occur also on the tubes. 



Boletus punctipes PA-. 

 Punctate -stemmed Boletus. 



Pileus convex or nearly plane, glutinous when moist, yellow, the 

 thin margin at first minutely grayish-pulverulent, becoming recurved 

 with age ; tubes short, nearly plane, adnate, small, subrotund, at first 

 brownish, becoming sordid-ochraceous ; stem rather long, tapering 

 upwards, not annulate, glandular-dotted, rhubarb-yellow ; spores 

 .00035 to .0004 in. long, .00016 to .0002 broad. 



Plant gregarious, pileus 2 to 3 in. broad, stem 2 to 3 in. long, 3 to 

 5 lines thick. 



Woods. Gansevoort, Saratoga county. August. 



The rhubarb-colored stem and the brownish color of the young 

 hymenium are the distinguishing features of this species. The granu- 

 lations occur also on the tubes. The species is a rare one, having 

 been found but once. 



Boletus' albus Pk. 

 White Boletus. 



Pileus convex, viscid when moist, white, flesh white or yellowish ; 

 tubes plane, rather small or medium size, subrotund, adnate, whitish, 

 becoming yellow or ochraceous ; stem equal or slightly tapering down- 

 wards, not annulate, both it and the tubes glandular-dotted, white, 

 sometimes tinged with pink towards the base ; spores ochraceous, sub- 

 fusiform, .0003 to .00035 in. long, .00016 broad. 



Plant gregarious or subceespitose, pileus 1.5 to 3 in. broad, stem 

 1.5 to 3 in. long, 3 to 5 lines thick. 



Pine or hemlock woods. Saratoga county and Adirondack moun- 

 tains. August to October. 



This species is easily known by its white pileus. This, however, 

 becomes dark-colored or brown in drying. The fresh plant sometimes 

 has a peculiar fetid odor, but it does not appear to be constant. 

 Boletus Boudieri Q. is a closely related European species. Another 

 European species bears the name Boletus albus Gillet, but the name 

 of the American plant, which was published in 1873, has priority.
