BOLETI OF THE UNITED STATES I51 
HYPORHODII | 
Tubes adnate to the stem, whitish, then white-incarnate 
from the rosy spores. 
In this tribe the tubes are at first whitish, but with the 
development of the spores they usually assume a pinkish or 
flesh-colored hue. Wounds of the tubes in some species 
cause a change in color but not to blue, nor are the tube 
mouths differently colored as in the Luridi. The stem in 
some is more or less reticulated but this is scarcely a con- 
stant or reliable character in these species. Typically the 
spores are rosy or flesh-colored, but I have admitted species 
in which they incline to ferruginous, giving more weight to 
the color of the tubes than to that of the spores.
