at first yellow, concealed by a reddish glutinous membrane, then 

 ochraceous, convex, large, angular, adnate ; stem nearly equal, annu- 

 late, yellow above the annulus, red or red with yellow stains below ; 

 s^OYQ^jjiuylLsh-broivn, .0005 to .0006 in. long, .00025 to .00028 broad. 



Pileus 2 to 5 in. broad, stem 3 to 5 in. long, 4 to 6 lines thick. 



Thin woods in swamps. Adirondack mountains. August. 



This rare and showy species is at present known only from two 

 localities, North Elba, where it was first discovered in 1869, and at 

 Jacksons, near Cedar river, where it occurred in 1878. When cut 

 the flesh emits a strong, unpleasant odor. Wounds of the flesh, made 

 by insects or small animals, had a bright-yellow color. When 

 young, the tomentose veil covers the whole plant, but it soon breaks 

 up into scales on the pileus, and partly or wholly disappears from the 

 stem. The color of the spores is darker than in any of the other 

 species of this section. 



Boletus Elbensis Pk. 



Elba Boletus. 



Pileus gibbous or convex, smooth, viscid when moist, dingy-gray 

 or pinkisk-gray, obscurely virgate-spotted, flesh white ; tubes at first 

 wldlish, nearly plane, adnate or slightly decurrent, rather large, an- 

 gular, becoming dingy or brovvnish-ochraceous ; stem nearly equal, 

 annulate, whitish ahove the annulus, colored like the pileus below, 

 sometimes slightly reticulated at the apex by the decurrent walls of 

 the tubes ; spoves ferruginous-broiv?i, .0004 to .0005 in. long, .00016 

 to .0002 broad. 



Plant subgregarious, pileus 2 to 4 in. Inroad, stem 3 to 5 in. long, 

 4 to 6 lines thick. 



Thin woods of larch, spruce and balsam. Adirondack mountains. 

 July to Se[)tember. 



This species is so closely related to the European B. laricinus, that 

 it might almost be regarded as a variety of that species. I have 

 separated it Ijecause of its smooth pileus and stem. I have never 

 seen the former squamose, nor the latter scrobiculate. From B. 

 viscidus it diflers decidedly in its coloration.
