PoiTPonus DttTOPHiLus : pileo crasso, rigido, ungulato, scabroso, insequa- 

 bili, incano-ferrngineo-flavo : contextu cinnamomeo, hymeniocinnamomeo-fus- 



co, poris parvis, intus rhabarbarinis. Pilei subimbricate, four inches broad, 



three inches long, ungulate, unequal, rough with scabrous points formed by in- 

 nate pubescence of a ferruginous yellow^, but subdued by a thin white film ; 

 substance fibrous, hard, cinnamon ; pores externally cinnamon-brown, within 

 ferruginous yellow, about one-eightieth of an inch broad, angular, with thin 



dissepiment. Nearly allied to Polyporus dryadeus, but a smaller, more 



rigid species with larger, differently colored pores. It has also much resem- 

 blance to Polyporus gilvus. 



^ A small variety not exceeding an inch in breadth, and the third of an inch 

 in length. 



3 Nothing can well be more different than the pure white, adult individuals 

 and the elegantly brown-zoned plant, looking like some states of Thelephora 

 evolvens, before the pores are formed. Occasionally the whole of the uppe 

 surface is clothed with a cracked brown stratum, not disposed at all in zones

303. Forming a compact, globular mass, four or five inches in diameter 



consisting of closely pressed curved, imbricating pilei, united at the base into 

 a mottled mass consisting of bark highly impregnated with mycelium, pur 

 plish-brown behind, where it is laccate with a dark bloom, pallid in front 

 substance corky, rather soft, ferruginous; hymenium concave, scarcely con- 

 spicuous without dividing the pilei, brown; pores minute, punctiform, pale 

 within; interstices even, obtuse. The mass behind is sometimes perforated 

 by the larva of some insect, which makes large channels through it. Very 

 fragrant when fresh ; odor a combination of pine apple and strawberry, very 



perceptible at a distance of tvi^enty yards from the tree. The specimen on 



Hickory was of a fine ochre-red, and the hymenium purplish. Allied to
