Forty-second Annual Report on the 



This has the habit and color of T. laciniata, but it forms tufts of 

 branches rather than pilei and the hymenium is even. Sometimes it 

 overtops the stems which it incrusts and then it appears stipitate and 

 branched above. 



Corticium sulphur eum, Fr. 



Prostrate trunks of balsam. North Elba. Sept. 



Corticium rhodellum, n. sp. 



Thin, membranous, adnate; subiculum and fimbriate margin white 

 or whitish; hymenium slightly pruinose, rosy-incarnate, bearing 

 metuloids .0016 to .002 in. long, .0004 to .00045 broad; spores 

 elliptical, naviculoid, .00016 to .0002 in. long. 



Decaying wood. Lyndonville, Orle.ans county. G. E. Fairman, M. D. 

 Specimens have also been found growing on the bark of poplar and 

 communicated to me by Mr. T. G. Gentry of Philadelphia. 



The species differs from C. carneum B. & C. in its brighter color 

 and in the even, not rimose, hymenium. From G. roseum Pers. it is 

 distinct by the presence of metuloids and its smaller spores. It 

 belongs to the genus Peniophora of Cooke. 



Corticium subincarnatum, n. sp. 



Effused, thin, pale-yellow, soon subincarnate, even, pruinose-pul- 

 verulent, the broad scarcely determinate margin sulphur yellow; 

 spores elliptical, minute, .00016 in. long, .00008 broad. 



Decorticated wood of spruce. North Elba. Sept. 



Hymenochaete abnormis, n. sp. 



[Plate l. Figs. 13-16.] 



Pileus effuso-reflexed, coriaceous or subcorky, about six lines broad, 

 generally imbricated and wavy or complicate, tomentose, obscurely 

 zonate, sometimes tuberculate or uneven, blackish; hymenium cin- 

 ereous, pruinose, setulose with pale-ferruginous blunt setse; spores 

 oblong, colorless, .0004 to .0005 in. long, .0002 to .00025 broad. 



Decaying wood of spruce in wet places. Adirondack mountains. 

 Sept. 



Remarkable for the colored but unusually blunt and subcylindrical 

 setae of the hymenium. These are sometimes paler above and some- 

 times slightly rough. 



Pistillaria viticola, n. sp. 



[Plate 2. Figs. 2S-27.] 



Club ovoid or obovoid, obtuse, glabrous, white, about equal to or 

 only half as long as the stem; stem cylindrical or slightly tapering 

 upward, glabrous, .5 to. 75 line long, white; spores elliptical, .00025 to 

 .0003 in. long. 



Dead stems of grape vine, Vitis cestivalis. Ellen ville, Ulster county.
