Report of the State Botanist. 91 



This species is remarkable for the abundance of its spores. It is so 

 deformed and apparently imperfect in its development that such fruit- 

 fulness would scarcely be expected. The pileus, when sufficiently de- 

 veloped to be recognizable, is ot a reddish or alutaceous color. 



Polyporus epileucus, Fr. var. candidus, Ph. 



Decaying prostrate trunks of hemlock, Abies canadensis: Osceola, 

 Lewis county. Aug. 



Pileus snowy-white, scrupose, scarcely villose, somewhat fibrous 

 within and slightly zonate toward the margin ; pores plane or convex. 



Our specimens, while not agreeing fully with the published characters 

 of P. epileucus, approximate so closely to them that we have character- 

 ized this form as a variety. 



Polyporus crispellus, n. sp. 



Pileus thin, fleshy, laterally elongated, undulate or subcrispate on the 

 margin, radiate-rugose, subglabrous, whitish varied with brownish zones, 

 flesh white, marked by a few linear hyaline or slightly colored zones ; 

 pores short, about equal in length to the thickness of the pileus, minute, 

 subrotund, white, the thin dissepiments more or less dentate. 



Pileus 8 to 12 lines broad, extending laterally i to 4 inches. 



Prostrate trunks of hemlock. Osceola. Aug. 



Closely allied to P. destructor, but distinguished by its zonate pileus 

 and short pores. It is also apparently thinner and more undulate than 

 that species. 



Polyporus (Physisporus) laetificus, n. sp. 



Effused, thin, tender, not readily separable from the matrix, bright 

 orange with a subtomentose yellowish margin , tubes short, often oblique 

 minute, subrotund, the dissepiments thick, obtuse. 



Decaying wood. South Ballston. Aug. 



The fungus forms patches two or three inches long, following the ine- 

 qualities of the surface. In the dried state the pores appear like little 

 ruptured vesicles as in P. vesiculosus, B. & C. The species ap- 

 pears to approach P. fulgens, Rost., which has the margin white fibril- 

 lose and the pores acute. 



Polyporus (Physisporus) griseoalbus, n. sp. 



Effused, thin, tender, adnate, uneven, scarcely margined, indetermi- 

 nate, grayish-white, with a thin pulverulent subiculum ; pores very 

 minute, subrotund, often oblique. 



Soft decaying wood of deciduous trees. Osceola. July. 



The pores are sometimes collected in little heaps or tubercles as in 

 P. molluscus and P. Vaillantii. In the dried state they are slightly 

 tinged with creamy yellow. 



Polyporus (Physisporus) fimbriatellus, n. sp. 



Widely effused, thin, tenacious, separable from the matrix, with a thin 

 white fimbriate margin and a white subiculum, running into rhizomor-
