Clitopilus Underwoodii -'/. sp. 



Pileus rather thin but fleshy, nearly plane or slightly depressed in the 

 center, even, whitish ; lamellae narrow, close, slightly decurrent, pale 

 flesh-colored ; stem rather short, equal or slightly tapering upward, solid 

 whitish; spores subglobose, .00016 to .0002 in. long. 



Pileus 6 to 18 hnes broad; stem about i inch long and 2 hnes thick. 



Syracuse and Jamesville. September and October. Z. M. Underwood. 



From the resemblance of our plant to Cooke's figure 599, representing 



a variety of C. stilbocephala, it was referred in the Forty- third Report, p. 



18, to this species as a variety. But the variety figured by Cooke has 



since been shown to be quite distinct from C. stilbocephala, and has been 



published under the name Clitopilus Smithii. Our plant approaches this 



species but differs in some points and especially in its short solid stem. 



I have therefore described it as a distinct species, dedicating it to its 



discoverer. 



Eccilia nivea //. sp. 



Pileus submembranous, hemispherical or very convex, glabrous, slightly 

 umbilicate, white; lamellae thin, distant, arcuate, decurrent, white 

 becoming pinkish; stem slender, glabrous, hollow, white; spores angular 

 or irregular, uninucleate, .0003 in. long and nearly as broad. 



Pileus 4 to 6 lines broad; stem i to 1.5 in. long, scarcely i line thick. 



Damp ground in thin woods. Selkirk. September. 



The only white species of Eccilia which I find described is E. acus 

 Smith. It differs from our plant in its deeply umbilicate and densely 

 pruinose pileus and its oblong angular spores. 



Hebeloma gregarium ;/. sp. 



Pileus fleshy but thin, hemispherical or convex, obtuse or rarely with a 

 small inconspicuous umbo, slightly viscid when moist, glabrous or 

 sHghtly silky on the margin from the remains of the veil, pale ochraceous- 

 yellow, sometimes with a slight reddish or tawny tint in the center, flesh 

 whitish; lamellae thin, close, adnate, at first whitish, then subcinnamon; 

 stem slender, stuffed or hollow, whitish, fibrillose, slightly mealy or prui- 

 nose at the top; spores elliptical, .0004 to .00045 '"• lo"g> .00024 broad. 



Pileus 8 to 16 lines broad; stem 1.5 to 2 in. long, i to 2 lines thick. 



Sandy soil in heathy places. Delmar. October. 



This small species belongs to the section Pusilli. The pileus is some- 

 times longitudinally rimose, and sometimes split on the margin in such a 

 way as to cause it to appear stellately lobed. Sometimes a colored band 

 appears on the stem by reason of the spores lodging on the slight adher-
