The species is closely related to. L. granulatus, from which it differs 
especially in its copious gluten, darker-colored pileus, shorter stem, 
and in the almost entire absence of granules from the tubes and 
stem. When present they are limited to the upper part of the stem 
and are extremely minute and inconspicuous. It occurs very late in 
the season, £B. véscosus Frost is a synonym. 
Boletus badius Ff’. 
Bay Boletus. 
Pileus convex, even, soft, viscid or glutinous when moist, some- 
what shining when dry, tawny or chestnut color, flesh whitish tinged 
with yellow, bluish next the tubes; tubes rather long and large, 
angular, adnate, s¢uwate-depressed, whitish-yellow, becoming tinged 
with green; stem hearly equal, rather long, even, paler than the 
pileus, Jrownish-pruinose ; spores oblong, .0004 to .0005 in. long, 
.00016 to .0002 broad. 
Pileus 2 to 3 in. broad, stem 2 to 4 in. long, 3 to 5 lines thick. 
Woods. Rensselaer and Lewis counties. August and September. 
The dimensions of the spores are derived from the American plant. 
They are smaller than those given by Karsten for the European 
plant. We have observed no greenish hue to the tubes nor bluish 
color to the flesh, and to this extent cur specimens are doubtful. 
The pliant needs further examination. 7 
Boletus piperatus Bull. 
Peppery Boletus. 
Pileus convex or nearly plane, smooth, slightly viscid when moist, 
yellowish, cyinamon or subferruginous, flesh white or yellowish, taste 
acrid, peppery ; tubes rather long and large, angular, plane or con- 
vex, adnate or subdecurrent, reddish-ferruginous, generally more 
highly colored than the pileus: stem slender, nearly equal, tawny- 
yellow, bright-yellow at the base ; spores ferruginous-brown, subtusi- 
form, .00085 to .00045 in. long, .00016 broad. 
Pileus 1 to 3 in. broad, stem 1.5 to 3 in. long, 2 to 4 lines thick. 
Woods and open places. Common and variable. July to October. 
‘Lhe species is readily known by the peppery taste of the flesh, and 
the bright yellow color of the base of the stem. ‘The pileus is some- 
times rimose-scaly or rimose-areolate. It is less viscid than most other 
species of this section. The color of the spores is similar to that 
of the spores of L. Kibensis. LB. ferruginatus Batsch, is a synonym.
