BOLETI OF THE UNITED STATES 131 
Pileus 2 to 4 in. broad; stem 2 to 3 in. long, 1 in. thick. 
Woods. North Carolina, Curtzs. 
Although apparently distinct, this and the two preceding 
species are not sufficiently well known. 
EDULES 
Tubes subfree, rounded-depressed around the stem, their 
mouths not at first reddish, but commonly white-stuffed. 
Stem stout, bulbous as in the Luridi, but not, with a few 
exceptions, reticulate nor punctate-squamulose nor red. 
Flesh scarcely changeable. Taste pleasant. 
This tribe is not sharply limited but partakes to some 
extent of the characters of Calqpodes and Luridi. From 
the former, its nearly free and at first white-stuffed tubes 
and its generally even stem separate it, from the latter its 
tubes with concolorous mouths or at least with mouths not 
red or reddish when young will distinguish it. The species 
are generally of large or medium size and noted for their 
esculent qualities. 
Stem brownish-lilac or chocolate color. ......... I
