Polyporus Isidioides, Berk. — On a large dead beech. Cincinnati, 

 Sept. 17, 1842.* 



Polyporus adustus, Fr. — On a mulberry stump. Cincinnati, Oct. 

 14, 1841, Sept. 15, 1842. 



Were not Pol. adustus so very variable this would doubtless be con- 

 sidered a distinct species. It is of a } r ellow brown tint, velvety, with 

 a few distant zones, the margin white, rigid when dry, substance zoned: 

 the pores are while and veiy shallow. It has a fetid odor when drying. 

 The common form also occurs. 



Polyporus nigro-purpurascens, Schwein.-«-On dead trunks. Waynes- 

 ville, Aug. 31, 1844. 



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

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

 named is P. dichrous, Fries. 



Polyporus endocrocinus, n. sp. — On the decayed part of the trunk 

 of a yellow hickory. Waynesville, Aug. 29, 1844. 



Pileo crasso, carnoso-fibroso, setis strigoso-horrido, brunneo ; con- 

 textu croceo rhubarbarino ; stipite brevi vel obsoleto ; hymenio aureo- 

 fusco ; poris mediis, laceratis ; dissepimentis tenuibus. 



Pileus thick, four to six inches across, of a fleshy fibrous con- 

 sistence, absorbing much moisture, dark brown, clothed with strigose, 

 flat, lacerated setae or scales ; substance 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. tichweintzii, but is distinguished 

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

 Two specimens only were found. 



Polyporus galactinus, n. sp. — On rotten trunks. Waynesville, 

 Aug. 29, Sept. 10, 1844. 



Pileo dimidiato, carnoso, molli, inaequabili strigoso-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 strigose down, of a soft fleshy substance, zoned 

 within and consisting of radiating fibres; hj'menium flat, or slight!}' 



* Berk, in Zeyher's Fungi, from Uitenhage. — Hook. Loud- Joura. This species is per 

 haps too near Pol. gilvus.
