at first yellow, concealed by a reddish glutinous membrane, then 
ochraceous, convex, /arge, angular, adnate ; stem nearly equal, annu- 
late, yellow above the annulus, red or red with yellow stains below ; 
spores purplish-brown, .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 Ph. 
Elba Boletus. 
Pileus gibbous or convex, smooth, viscid when moist, dingy-gray 
or pinkisk-gray, obscurely virgate-spotted, flesh white ; tubes at first 
whitish, nearly plane, adnate or slightly decurrent, rather large, an- 
gular, becoming dingy or brownish-ochraceous ; stem nearly equal, 
annulate, whitish above the annulus, colored like the pileus below, 
sometimes slightly reticulated at the apex by the decurrent walls of 
the tubes ; spores ferruginous-brown, .0004 to .0005 in. long, .00016 
to .0002 broad. 
Plant subgregarious, pileus 2 to 4 in. broad, stem 3 to 5 in. long, 
4 to 6 lines thick. 
Thin woods of larch, spruce and balsam. Adirondack mountains. 
July to September. 
This species is so closely related to the European B. laricénus, that 
it might almost be regarded as a variety of that species. I have 
separated it because of its smooth pileus and stem. I have never 
seen the former squamose, nor the latter scrobiculate. From JD. 
viscidus it differs decidedly in its coloration.

Pileus thick, convex, very viscid or glutinous, smooth, soft, shining, 
varying in color, golden-yellow, reddish-yellow or chestnut-color, the 
margin thin, flesh pale-yellow, becoming less bright or dingy on ex- 
posure to the air; tubes nearly plane, adnate or subdecurrent, small,
