34 Thirty-second Report on the State Museum. 



P. parvulus, but the ferruginous or tawny color of P. perennis. I have 

 seen only poor deformed specimens, and for the present prefer to consider it a 

 variety of the above under the name P. parvulus var. deformatus. 



POLYPORUS SIMILLIMUS ft. Sp. 



Pileus thin, coriaceous, convex or expanded, umbilicate, zonate, cinereous- 

 brown or livid-chestnut color, slightly silky-tomentose and radiately-fibrillose ; 

 pores minute, angular, not at all or but slightly decurrent, cinnamon-color, 

 the dissepiments thin, acute, toothed or lacerated ; stem slender, equal, 

 sometimes slightly bulbous at the base, slightly velvety-tomentose, brownish; 

 spores elliptical, usually uninucleate, .00025 -.0003' long, .0002' broad. 



Plant about 1' high, pileus 6 "-12 ' broad. 



Burnt ground. Brewerton. Sept. 



This plant occurred in company with the preceding species, and was at 

 first taken to be a mere variety of it. Looking at the upper surface of the 

 pileus alone it is not possible to separate one species from the other. But 

 there is such a marked difference in the size of the pores and in the length of 

 the spores that it scarcely seems right to lump the two together as one species. 

 The spores are scarcely as large as in P. splendens and P. perennis, and 

 they sometimes exhibit a slight incarnate tinge. In all the four species men- 

 tioned the pilei are sometimes confluent and sometimes have the margin fim- 

 briate. P. pictus, another closely related species, but one which has not 

 yet occurred with us, may be distinguished from the others by its glabrous 

 stem. 



The prominent characters of our four species may be expressed as follows : 



Pileus plane or convex, umbilicate, opake. 



Pores large, rather long-, scarcely decurrent P. parvulus Klotsch. 



Pores small, rather long-, scarcely decurrent P. simillimus Pk. 



Pileus plane or convex, umbilicate, shining", pores small, 



scarcely decurrent P. splendens Pk. 



Pileus plane or infundibuliform, opake. pores short, small, 



decurrent-. .' P. perennis Fr. 



POLYPORUS CIRCINATUS Fr. 



Ground in the borders of woods. Brewerton. Sept. 



Polyporus Morgani Frost MS. 



Pileus fleshy, plane or convex, hairy-tomentulose, subsquamulose, reddish 

 or brownish, the margin thin ; pores short, medium size, subrotund, decur- 

 rent, white ; stem subequal, elastic, solid, radicating, the subterranean 

 portion black or blackish-brown, the exposed part whitish or pallid, inclin- 

 ing to tawny, velvety or somewhat reticulated, central or eccentric ; spores 

 oval, pointed at one end, .0005' long, .0003' broad; flesh white. 



Plant 3'-5' high, pileus 3-4' broad, stem 3"-5 7 thick. 



Ground in woods. Buffalo Clinton. Brewerton. Sept. 



This species is evidently closely allied to P. radicatus Schw., and P. 

 melanopus Fr., but it is in some respects quite diverse from the figure and 

 description of the latter species. The stem sometimes penetrates the earth 

 to a considerable depth, and is quite probably attached to decaying roots or 

 buried pieces of wood. The flesh of the pileus is sometimes quite thick.
