Hymenophore even. Tubes not 

 easily separable from it, large, 

 equal. Pileus and stem distinctly 

 rough-scaled, the flesh tough. Syl.

I have given Professor Saccardo's 

 emended diagnosis of this genus, 

 because it expresses what appears 

 to me to be the most important 

 generic character, that is, tubes not 

 easily separable from the hymeno- 

 phore. By this character and by 

 the tough substance the transition 

 between Boletus and Polyporus is 

 made. 



Tubes nearly equal in length 



Tubes shortened around the stem. . .

S. strobila'ceus Berk. Gr. cone-like. (Plate CXXIV.) Pileus 

 hemispherical or convex, dry, covered with thick floccose projecting 

 blackish or blackish-brown scales, the margin somewhat appendiculate 

 with scales and fragments of the veil. Flesh whitish, changing to 

 reddish and then to blackish where wounded. Tubes adnate, whitish, 

 becoming brown or blackish with age; their mouths large, angular, 

 changing color like the flesh. Stem equal or tapering upward, sulcate 

 at the top, floccose-tomentose, colored like the pileus. Spores sub- 

 globose, rough, blackish-brown, 10-12.5^.
