136 THIRTY-FIFTH REPORT ON THE STATE MUSEUM. 
PoLyporus (PLACODERMEIL) FRAXINOPHILUS, Pk. 
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 suleate, rimose, the substance within obscurely 
zoned, at first whitish, then isabelline or pale-tawny, 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 see Coey- 
mans, Albany county. May and September. 
The species belongs to the tribe Pomentarii, 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, 
IrnPEX crassus, B. and C. 
Oak stumps. North Greenbush. October. 
IRPEX MOLLIS, B. and C. 
Decaying wood. Helderberg mountains. October. 
The teeth in this species are sometimes compressed in such a 
manner that they appear like radiating lamelle broken up into 
narrow segments. They have acoarse 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 
I. lacteus. 
CoRTICIUM EFFUSCATUM, (7. and £. 
Dead branches. East Berne. August. 
THELEPHORA ROSELLA, 7. Sp. 
Very small, tufted, 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, Alnus 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, 7. 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.
