lamellae thin, narrow, close, adnate, whitish when young, becom- 
ing black; stem slender, weak, flexuose, never erect, hollow, 
white; spores broadly elliptical, .oo05 in. long, .0003 broad;

BOLETUS TABACINUS. 
Pileus fleshy, convex or nearly plane, subglabrous, often ri- 
mose-areolate, tawny-brown, flesh at maturity soft and similarly 
colored; tubes concave or nearly plane, depressed around the 
stem, their mouths small, angular, colored like the pileus; stem 
subequal, solid, reticulated, concolorous; spores oblong oF sub- 7 
fusiform, .0005 to .00055 in. long, about .0002 broad; pileus 2-5 _ 
to 5 in. broad; stem 1.5 to 3 in. long, 6 to 10 lines thick. ES 
Along roadsides. Alabama. May. Underwood. : 
The species is referable to the section Calopodes, but the tubes 
are more or less depressed about the stem. It is well marked by — 
its color which is some shade of brown or tawny-brown through : 
out, inclining at one time toward wood-brown, isabelline-brown OF — 
broccoli-brown, at another toward sepia-brown, The flesh in the : 
dried specimens appears a little darker than the surface of the 
pileus. It is almost tomentose in texture. 2
