' Berk, in Zeyher's Fungi from Uitenhage. — Hook. Land. Journ. Tliis spe- 

 cies is perhaps too near Pol. gilvus. 



^ Were not Pol. adustus so very variable this would doubtless be considered 

 a distinct species. It is of a yellow-brov^n tint, velvety, with a few distant 

 zones, the margin white, rigid when dry, substance zoned ; the pores are white 

 and very shallow. It has a fetid odor when drying. The common form also 

 occurs. 



3 Pores at first salmon-colored or brownish, in older specimens yellowish- 

 white. This, if my specimen from the south of Europe is properly named, is 

 P. dichrous, Fries. 



* PoLTPORUs ENDOCROcisus : pilco crasso, carnoso-flbroso, setis strigoso- 

 horrido, brunneo; contexta croceo-rhubarbarino ; stipite brevi vel obsoleto ; 



hymenio aureo-fusco; poris mediis laceratis; dissepimentistenuibus. Pileus 



thick, four to six inches across, of a fleshy-fibrous consistence, absorbing much 

 moisture, dark-brown, clothed with strigose, flat, lacerated setae or scales ; sub- 

 stance of a rich saffron; hymenium golden-brown; pores one-sixtieth of an 



inch broad, angular, with the edge of the thin dissepiments torn or fringed. 



This species shrinks much in drying. It is allied to Pol. Schiveintzii, but is 

 distinguished by its saffron colored substance, and its strigoso-squamose pileus. 

 Two specimens only were found. 



* PoLYPORUs GALACTINUS : pileo dimidiato, carnoso, molli, insequabili stri 

 goso-tomentoso, lacteo, intus zonato, fibroso, margine tenui ; poris parvis albis. 



Pileus two to three inches broad, one and a half inches long, dimidiate or 



uniform and elongated behind, convex, uneven, milk-white, clothed with stri- 

 gose down, of a soft fleshy substance, zoned within and consisting of radiating 

 fibres; hymenium flat, or slightly concave ; pores one-hundredth of an inch 

 broad, scarcely visible to the naked eye, but giving to the hymenium a silky 



lustre, white; dissepiments very thin, slightly uneven. Nearly allied to 



Pol undulatus, Schwein. and Pol. symphyton, Schwein. The dried specimens 

 are rigid, and sometimes have the margin dark-brown.
