PALLIDUS. CONTEXT PALE. 



annosus in context color and surface color, but differs in its peculiar 

 shape, and pore development. The pores of the species form contin- 

 uous layers, as is usual in Fomes, not separate and independent layers, 

 as in Fomes annosus. The type specimens are two to three inches 

 wide, but the collector states that it "grows very large." 



SECTION 57. SMALL. CONTEXT WHITE OR ISABELLINE. 



\Yc include in this section Fomes ohiensis, which really forms a section of 

 itself. It has large, obovoid, truncate, hyaline spores, similar (except color) to the 



spores 



that characterize the section Ganodermus. No other known Fomes has 



riilar spores, but Polyporus ochroleucus does have such spores, and in a natural 

 arrangement should be classed in same section with Fomes ohiensis. 



FOMES OHIENSIS. Pileus small, dimidiate, usually less than 

 2 cm. in diameter, > cm. thick, white, hard. Surface smooth, even, 

 with no distinct crust. Context and pores white. Pores small, round, 

 regular. Spores obovate, truncate at base, hyaline, smooth, 8x12-14. 



This is quite a frequent little species in Ohio, growing around 

 Cincinnati, usually on rail fences, rarely on logs in the woods. At 

 New York there is a collection from Cuba, and Romell records it 

 from Brazil. But one collection is so referred from Europe, sent to 

 me from Portugal by Rev. Torrend, but I can not be sure it is not a 

 small specimen of Polyporus ochroleucus. It is unknown from the 

 East being replaced there by Polyporus ochroleucus. 



SPECIMENS. A dozen from Ohio, mostly my own collections, one collection from Da- 

 kota, Dr. J. F. Brenckle, but not elsewhere have I gotten this typical form. 



Large form. There occurs in New York State a larger form than the usual 

 Ohio form. I have a specimen Ixlxl^ inches. I have only seen one collection 

 of it from the west. 



SPECIMENS. New York, L. H. Weld, D. Reddick; Ohio, Hurt Leeper. 



FOMES SCUTELLATUS. Pileus ligneous, usually scutellate 

 from position of growth on underside of branches, rarely dimidiate, 

 small, usually about a cm. in diameter. Surface rugulose, dark brown 

 or black. Context isabelline. Pores minute, the tissue isabelline, but 

 mouths, when fresh, white. Spores not found by me. 



This little species is American only, as far as known. It grows 

 usually on under side of alder, .hazel, and other soft wood branches, 

 lying on the ground in moist places. It is common in the swamps of 

 our northern and eastern States. I do not find spores even in freshly- 

 collected material. Fomes scutellatus is well named, for in every col- 

 lection I have, excepting one, all specimens are scutellate. It is rarely 

 dimidiate. Morgan confused Fomes ohiensis under the name Fomes 

 scutellatus. 



SPECIMENS. Eight collections all from the north, Canada, Michigan, or the east, New 

 York, Vermont, etc.
