THE WHITE-SPORED AGARICS 



221 



The gills are subdistant, adnate, or decurrent, white or creamy-white. 



The stem is five to ten Cm. long, firm, solid, white. 



The spores are elliptical, 6.5-7.5x4-5//,. Peck. 



The specimens I found were clear white, growing among leaves and were 

 especially free from soil. The stems were short and were inclined to be slightly 

 ventricose. Dr. Peck says that this "species is distinguished from H. penarius 

 by its clear white color, though this is commonly obscured by the adhering dirt 

 that is carried up in the growth of the fungus." The young, growing plants were 

 strongly involute but the older plants were reflexed, giving the plants a funnel- 

 shaped appearance and giving the gills a much stronger decurrent appearance. 

 Found October 26th. 



Hygrophorus serotinus. Pk 

 Late Hygrophorus. 



Serotinus means 

 late. So called be- 

 cause it is late in the 

 season. 



Pileus is fleshy but 

 thin, convex or nearly 

 plane, often with the 

 thin margin curved 

 upward, glabrous or 

 with a few obscure in- 

 nate fibrils, reddish in 

 the center, whitish 

 on the margin, flesh 

 white, taste mild. 



The gills are thin, 

 subdistant, adnate or 

 decurrent, white, the 

 interspaces slightly 

 venose. 



The stem is equal, 

 stuffed or hollow, glabrous, whitish 

 inch long, .0002 broad. 



Pileus is 8-15 lines broad; stem about 1 inch long, 1.5-2.5 lines thick. Peck. 



Some specimens of this species were sent to me from Boston by Mrs. Blackford, 



but after a careful study of them I was unable to place them. She then sent 



them to Dr. Peck, who gave them their very appropriate name. Those in Figure 



177 were sent me in December, 1907.
