at the top, 2.5-5 cm. thick at the base.

This Boletus agrees so closely with B. purpureus in all its char- 
acters except color that it has seemed best to consider it a mere 
variety of that species, but future investigation may show it to be 
a distinct species. It does not appear to have any purple hues in 
either pileus or stem.

_ * Boletus scabripes Peck, sp. nov. Pileus thick, broadly con- 
vex, firm, dry, glabrous, reddish-brown with a bloom; tubes con- 
vex in the mass, adnate or slightly depressed around the stem, 
brown, with very small round darker mouths; stem stout, equal, 
solid but spongy within, grayish-white, adorned with numerous 
small projecting black points; spores oblong, fusiform, 12-15 4 
long, 4-5 » broad. 
Pileus about 15 cm. broad; stem about 1o cm. long, 2~3 cm.

Numerous, In drying the plants become black and exude a black 
juice with a strong odor. 
* BOLETUS SUBGLABRIPES Peck. In damp shady soil; only 
two plants found. 
Botetus sustureus Peck. Very plentiful all summer.
