SPORES HYALINE. 



We do not know in Europe a plant agreeing with Fries' description of Poly- 

 porus holmiensis, but we have one very abundant collection made at Albany New 

 York, on elm. It grew imbricate for a foot or more. When fresh it was white, but 

 in drying takes the characteristic color. It must be a rare form, for Prof. Peck never 

 met it. We have it also from Minnesota.

POLYPORUS AMESIL We have one marked collection of Polyporus 

 fumosus, that agrees exactly with the figure that Klotzsch gives, t. 392, of Polyporus 

 fumosus. The pubescence is stronger than in the usual plant, and the fuliginous 

 pileus is not due to a color change in drying, as ordinarily, but is evidently the natural 

 color of the growing plant. When we received it we matched with Klotzsch's figure 

 and decided that it was the true Polyporus fumosus. We have since, we think, 

 learned Polyporus fumosus better. 



SPECIMENS. Brooklyn, X. Y., Frank H. Ames. 



POLYPORUS FRAGRAXS. In the original signification, with large daeda- 

 loid pores, this was a fragrant form of Polyporus salignus. All this group of plants, 

 Polyporus fumosus and salignus, and even Polyporus adustus at times, have a frag- 

 rant odor, and they are all liable to be named Polyporus "fragrans." 



Compare puberula. 



POLYPORUS EPILEUCUS (Fig. 649). Pileus thin, white or 

 alutaceous, drying ochraceous, often with effused base. Surface 

 anoderm, rough. Flesh firm, tough, yellowish in dried specimens. 

 Pores small, round or elongated. Spores 2^4 x 5, reniform, hyaline, 

 smooth. 



This we believe to be a rare species. We found it on beech at 

 Femsjo, and it appears to corresppnd fairly well with Fries' descrip- 

 tion. We only know the plant from a few collections. When fresh it 

 was white, but became yellowish in drying. This plant in Europe has 

 been called Polyporus Hohenialus. We have collected once only, on
