lamellae; stem short, slender, firm, smooth or sprinkled with 

 minute mealy particles. 



Plant gregarious, white throughout, 8"-12" high, pileus 2"-4:" 

 broad. Bark of prostrate trunks in woods. Portville. Septem- 

 ber. 



Agaeicus (Mycena) koseocandidus Peclc. 



Pileus convex or broadly campanulate, subpapillate, striate 

 nearly to the apex, white or rosy-red ; lamellae close, uncinate, 

 white or rosy ; stem slender, smooth, wliite. 



Plant 2' high, pileus 4"-6" broad. 



Among mosses in woods. Adirondack Mts. July. 



Usually the whole plant is pure white, but sometimes the pileus 

 has a delicate rosy hue, except on the apex and margin. In such 

 specimens the lamellae are tinged with the same color, and the 

 delicate beauty of the whole plant can scarcely be surpassed. The 

 striations of the pileus are clearly seen in the dried specimens. 

 The papilla is sometimes very prominent, sometimes wanting. 



Agakicus debilis Bull. 



Under spruce and balsam trees, i^orth Elba. July. 



Agakicus eoridus Fr. 



Mossy ground in woods. ISTorth Elba. July. 



Agakicus pteeigenus Ft. 



Dead stems of ferns, Onoclea sensibilis. Sandlake. September. 

 The margin of the pileus as well as of the lamellae is sometimes 

 more highly colored than the rest of the plant. 



Agakicus (Omphalia) olivakius Peck. 



Pileus convex, umbilicate, smooth, yellowish-olive ; lamellae 

 arcuate, decurrent, subdistant, pale yellow ; stem equal, short, 

 smooth, hollow, colored like the pileus; spores subglobose or 

 broadly elliptical, .00026' long. 



Plant 1-1.5' high, pileus 1' broad, stem 1" thick. 



Burnt ground under balsam trees. North Elba. July. 



Agakicus gkacillimu^ Weinnfi. 



Dead twigs and leaves in wet places. Sandlake. September. 



Our plant does not agree strictly with the description, since the 

 lamellae are scarcely decurrent and the stem is slightly thickened 

 at the base where it is furnished with an abundance of radiating 

 flocci. It is at least a well marked variety, and may prove to be 

 a distinct species.
