Dr. Cooke says that the Granulated boletus has given him the 
greatest satisfaction as an edible species, and that he prefers it to 
the Edible boletus, or indeed to any other species that he has 
eaten. 
XVI. DRY BOLETI, POLYPORI AND FISTULINA. 
The Rough stem or Scabrous-stem boletus, Boletus scaber, is 
our most common species. Its cap varies in color from white to 
a dark brown or almost black. It is most often some shade of 
gray, varying to brick-red or pale orange. Its shape also varies 
from broadly and bluntly conical to convex or flat above, while 
its surface may be smooth or minutely downy or even obscurely 
scaly. Its flesh is white or whitish, both it and the mass of 
pores sometimes assuming 
pinkish orblackish hues where 
®% bruised or wounded. The 
pore stratum is at first whit- 
ish, becoming dingy brown 
with age. The pores are 
quite long, and the mass is 
convex below and muchshort- 
ened or depressed around the 
top of the stem. The stem is 
rather. long, often narrowed 
at or toward the top, solid, 
whitish, and dotted with nu- 
merous small fibrous scales or 
points which are reddish or 
blackish, and which are so 
small as to give a rough, dotted appearance to the stem. Some- 
times scales of both colors are seen on the same stem. This 
character is a peculiar one, and easily separates this species and 
the next from all their fellows. 
The plant having a white cap was first considered a distinct 
species and named Boletus niveus, but was afterwards made a va- 
riety of the Rough-stem boletus. It is sometimes still regarded as 
distinct. It is rare in this State.
