Scirpus pedicellatus Femald 

 Wet places and margins of lakes and streams. Lake Champlain, 

 along the railroad between Whitehall and Fort Ann and between Schuy- 

 lerville and Bemis Heights. July and^August. 



Scirpus atrocinctus Femald 

 Wet places. Lake Pleasant and Floodwood. Probably not rare in 

 the Adirondack region, but formerly confused with S. cyperinus. 

 Both this and the preceding species mature their fruit earlier than 

 S. cyperinus, and the long setae of their spikelets are paler. In 

 the present species the involucral bracts are blackish. In its variety, 

 brachypodus Fernald, the panicle is much contracted. Our speci- 

 mens of it were collected near East Worcester, about Lake Pleasant and 

 on Blue mountain, one of the Adirondack peaks. 



Elymus robustus S. b* S. 

 Near Riverhead. July. 



Dryopteris simulata J^av. 

 Maple swamp near Middle Village, L. I. September. G. D. Hulst. 



Stereocaulon nanodes luckm. 



Rocks. Along a stream flowing down the western side of Mt Mcln- 



tyre. July. The podetia are scarcely more than one or two lines high 



in our specimens. 



Stereocaulon pileatum Ach. 



Rocks. Top of Wall face mountain. July. 



Lepiota pulveracea n, sp, 



Pileus hemispheric, becoming convex or nearly plane, dry, pulverulent 

 or minutely granulose and squamulose, even on the margin, whitish or 

 pallid inclining to tawny; lamellae thin, close, adnexed, yellowish 

 white; stem equal, hollow, white and pruinose at the top, granu- 

 lose or squamulose below , the obsolete annulus and there colored 

 like the pileus ; spores minute, broadly elliptic or subglobose, .00016 of 

 an inch long, .00012 broad. 



Pileus about i inch^ broad; stem 1-2 inches long, 1.5-2 lines thick. 

 In woods on prostrate trunks of spruce trees. Floodwood. August. 

 Apparently related to L. granulosa by the adnexed lamellae but dis- 

 tinct in its color, habitat and minute spores.
