THE FUNGI WITH TEETH 



435 



Hydmim imbricatum. Linn. 

 The Imbricated Hydnum. Edible. 



Imbricatum is from imbrex, a tile, referring to the surface of the cap being 

 torn into triangular scales, seeming to overlap one another like shingles on a roof. 



The pileus is fleshy, plane, slightly depressed, tessellated scaly, downy, not 

 zoned, umber in color or brownish as if scorched, flesh dingy-white, taste slightly 

 bitter when raw, margin round. 



The spines are decurrent, entire, numerous, short, ashy-white, generally 

 equal in length. 



The stem is firm, short, thick, even, whitish. The spores are pale yellow- 

 brown, rough. 



The bitter taste entirely leaves the plant when well cooked. It seems to 

 delight in pine or chestnut woods. I found it in Emmanuel Thomas' woods, east of 

 Salem, Ohio. It is found from September to November.
