REPORT OF THE STATE BOTANIST 1905 27 



in the shape of the spores which are nearly globose and not at all 

 curved as in P. cruenta. 



Physoderma menyanthis DeBy. 



Living leaves of buck bean, Menyanthes trifoliata. 

 Bonaparte swamp, Lewis co. June. This species has been found 

 as far north as Alaska. 



Pluteus grandis n. sp. 



Pileus fleshy, firm, convex with the thin margin sometimes curved 

 upward, silky fibrillose, white or whitish, flesh white, taste farin- 

 aceous; lamellae thin, close, free, denticulate on the edge, whitish 

 becoming flesh-colored; stem rather long, equal, firm, solid, silky 

 fibrillose, white; spores subglobose, angular, uninucleate, .0003 of 

 an inch broad. 



Pileus about 4 inches broad; stem 4 inches long, 10 lines thick. 

 Among fallen leaves in woods. Bolton Landing. July. 



This is a fine large species, separable from E n t o 1 o m a 

 s i n u a t u m by its free lamellae, and from white forms of Plu- 

 teus cervinus by the angular character of the spores and by 

 its farinaceous taste. 



Polyporus underwoodii n. sp. Murr. 



Pileus varying from convex to deeply concave, 12-25 cm in 

 diameter, averaging .5 cm in thickness; surface obscurely con- 

 centrically zonate, milk-white, pruinose, cremeous on drying, the 

 center depressed and avellaneous; margin irregularly undulate 

 lobed, either deflexed or recurved, very thin, not ciliate; context 

 white, fleshy, tough, homogeneous, 2-5 mm thick; tubes milk-white, 

 2-3 mm long, five to six to a mm, cylindric, edges thin, entire to 

 lacerate; spores ellipsoidal, Ityaline, smooth, 3 x 6-7 m; stipe short, 

 central, solid, woody, equal or tapering downward, smooth, pruin- 

 ose, white above, fuliginous below, 3 cm long, 2-3 cm thick' 



The type of this species was collected by L. M. Underwood on buried 

 decaying roots beneath birch trees at Cornwall Ct., August 1890. 

 Specimens were also collected in Connecticut in 1 902 by C. C. Han- 

 mer. Fine specimens were again collected by H. C. Banker on the 

 roots of a fallen,' but living willow at Schaghticoke N. Y. in August, 

 1904. Plants were sent by Mr Bankertothe State Museum at Albany 

 and to the New York Botanical Garden. The nearest relative of this 

 species in our flora is probably Polyporus fissus Berk. 

 The specimen contributed to the State Musettm has the stem wholly 

 fuliginous.
