THE FUNGI WITH TEETH 



443 



Hydnum scrobiatlatitm. Fr, 



Scrobiculatum means marked with a ditch or trench ; so called from the 

 rough condition of the cap. The pileus is from one to three inches broad, corky, 

 convex, then plane, sometimes slightly depressed ; tough in texture, rusty-brown ; 

 the surface of the cap usually 

 quite rough, marked with ridges 

 or trenches, flesh ferruginous. 



The spines are short, rusty- 

 brown, becoming dark with age. 



The stem is firm, one to two 

 inches long, unequal, rusty- 

 brown, often covered with a 

 dense tomentum. 



This species is very plentiful 

 in our woods, among the leaves 

 under beech trees. They grow 

 in lines for some distance, the 

 caps so close together that they 

 are very frequently confluent. 

 I found the plant at Salem, and 

 in several other localities in the 

 state, although I 

 have never seen a 

 description of it. 

 Any one will be 

 able to recognize it 

 from Figure 371. It 

 grows in the woods 

 in August and Sep- 

 tember.
