136 Thirty-fifth Report on the State Museum. 



Polyporus (Placodermei) fraxinophilus, Pic. 



Pileus sessile, thick, corky, subtriquetrous, narrow, somewhat 

 decurrent behind, the first year whitish, with a minute whitish 

 tomentum or hairiness, then gray, finally blackish, in old specimens 

 concentrically sulcate, rimose, the substance within obscurely 

 zoned, afc first whitish, then isabelline or pale-fcawny, the margin 

 obtuse ; pores stratose, plane or subconvex, small, nearly equal, 

 subrotund, the dissepiments obtuse, entire, whitish ; spores 

 white, broadly elliptical, -0003' — 00035' long, -00025' — 0003' 

 broad. 



Pileus 2' — 4' long, 1' — 1-5' broad. 



Trunks and branches of dead or languishing ash trees. Coey- 

 mans, Albany county. May and September. 



The species belongs to the tribe Fomentarii, and is related by 

 its whitish pores and surface to P. connatus, but its colored sub- 

 stance and larger pores will easily distinguish it from that species. 

 Irpex crassus, B. and G. 



Oak stumps, North G-reenbush. October. 

 Irpex mollis, B. and G. 



Decaying wood. Helderberg mountains. October. 



The teeth in this species are sometimes compressed in such a 

 manner that they appear like radiating lamellae broken up into 

 narrow segments. They have a coarse stout appearance even when 

 most of them are subulate. The pileus is whitish and moist when 

 fresh. A resupinate form occurs, both of this species and of 

 J. lacteus. 

 Corticium effuscatum, G. and E. 



Dead branches. East Berne. August. 

 Thelephora rosella, n. sp. 



Very small, tirfted, rosette-like, variously laciniate, dentate or 

 subfimbriate on the margins, whitish or subincarnate, developing 

 from a blackish tubercle ; spores minute, narrowly elliptical or 

 sublanceolate, -0002' — 00025' long, scarcely half as wide. 



Dead branches of alder, A Inus incana. Sandlake. July. 



This is a very singular species, and may prove to be an imper- 

 fect condition of some fungus quite unlike this one. 

 Clavaria pinophila, n. sp. 



Stems short, more or less tufted, much branched; branches 

 crowded, often compressed above and subdigitately divided, pale- 

 ochraceous, ultimate ramuli rather long, subulate, white ; spores 

 oblong or sublanceolate, -0004' — 0005' long, -00016' broad. 



Thin woods under pine trees. East Berne. August. 



The tufts are about one inch high. The spores appear white 

 when caught on brown paper.
