REPORT OF THE STATE BOTANIST I907 1 49 



sinuate and having a decurrent tooth, whitish becoming brown or 

 rusty brown; stem equal or nearly so, stuffed or hollow, glabrous, 

 whitish, the annulus thick and cottony, often lacerated and evanes- 

 cent, white; spores broadly elliptic, .00024-.00028 of an inch long, 

 .00016-.0002 broad. 



Pileus 1-2 inches broad; stem 1-2 inches long, 2-4 lines thick. 



Rocky ground near Syracuse. August and September. G. E. 

 Morris, who has found it both in the locality given and in Massa- 

 chusetts. 



It is similar to P h o 1 i o t a dura (Bolt.) Fr. but may be sep- 

 arated from it by its different colors, softer substance and specially 

 by its smaller spores. These are more brown than the spores of 

 Pholiota praecox Pers. and make it doubtful whether the 

 species would not better be placed in the genus Stropharia. 



LIGNATIIiE 



Pileus viscid or dry, not hygrophanous 

 Pholiota albocrenulata Pk. 



CRENULATE PHOLIOTA 



Pileus fleshy, firm, convex or campanulate, obtuse or umbonate, 

 viscid, squamose, yellowish brown, the scales brown or blackish, 

 floccose, easily separable; lamellae broad, subdistant, sinuate, white 

 crenulate on the edge, grayish becoming ferruginous ; stem firm, 

 equal or slightly tapering upward, stuft'ed or hollow, squamose, pallid 

 or brownish below the slight fugacious annulus, white and fur- 

 furaceous above; spores subelliptic, pointed at the ends, .0004-.0005 

 of an inch long, .00024-.0003 broad. 



Pileus 1-3 inches broad ; stem 2-4 inches long, 2-5 lines thick. 



Base of trees or on prostrate trunks and decaying wood, specially 

 of sugar maple, Acer saccharum L. Essex and Otsego 

 counties. July and August. 



This species is rare and somewhat variable. It is never abundant 

 and often solitary in its mode of growth. The scales of the pileus 

 sometimes disappear leaving the surface of the cap mottled with 

 brown spots. Under a lens the edge of the lamellae appear as if 

 beaded with minute white globules. The margin of the pileus is 

 sometimes adorned by the adhering fragments of the veil.
