Polyporaceee 



On living and dead birch. Common. May to December. Poiypoms. 



Pileus 3-6 in. broad. The pileus is at first pale, then acquiring a 

 brownish tinge. The edge is always very obtuse. Stevenson. 



The lower surface or hymenium is frequently rough with numerous 

 acicular projections, making the plant look like a Hydnum when viewed 

 horizontally. Peck, 24th Rep. N. Y.. State Bot. 



Massachusetts, Kansas, New York. Peck, Rep. 24. 



Wherever the birch grows this neat, white-fleshed Polyporus abounds. 



When young it is eaten by deer. Dried it burns with a white flame, 

 or holds fire as well as the best punk. It is a valuable fuel, already 

 prepared for the stove. In the birch forests near Eagle's Mere, Pa., 

 tons of it can be seen protruding from tree and log. 



When very young it is fair. Unpleasant when old. 



V. RESUPINATI. 



P. sinuo'sus Fr. full of folds. Broadly effused, adnate, dry, the 

 evanescent mycelium somewhat rooting, white then yellowish. Pores 

 large, surface flexuous, acute, lacerated. Odor of licorice. 



New York. Decaying wood of maple. Peck, 4Oth Rep. 



Mt. Gretna, Pa. Mcllvaine. 



Of but little food value. Collected carefully and boiled, it yields a 

 pleasantly flavored liquor.
