No. 104.] 39 



villosity at the base; spores subgloboee or broadly elliptical, .C0016 

 to .0002 in. long. 



Pileus 4 to 8 lines broad, stem 1.5 to 3 in. long, about 1 line thick. 



Among moss and fallen leaves in open places in woods. Adiron- 

 dack mountains. Aug. 



The species should be referred to the section Tephrophanse.. 



Agaricus (CoUybia) esculentoides, n. sp. 



Pileus hemispherical or convex, umbilicate, glabrous, pale yellow- 

 ish-brown ; lamella? moderately close, broad, thick, whitish ; stem 

 slender, hollow, somewhat tenacious, colored like the pileus: spores 

 elliptical, .00025 to .0003 in, long, .0002 in. broad. 



Pileus 8 to 12 lines broad, stem 1.5 to 2 in. long, 1 to 1.5 lines 

 thick. 



Sandy soil. West Albany. Karner and Delmar. Sept. 



This species resembles A. escnlentus in size and color, but it differs 

 in its stem which is not radicated, and in its pileus which soon be- 

 comes umbilicate or more or less centrally depressed. It has a bitter 

 taste, a character attributed to A. esculentus also. Our plant 

 occurred in autumn, but A. esculentus is said to grow in early 

 spring. 



Agaricus (Mycena) amabiliissimus, n. sp. 



Pileus submembranous, campanulate, obtuse or acute, glabrous, 

 obscurely striatulate when moist, bright-red or scarlet; lamella? 

 ascending, whitish or tinged with red; stem slender, pallid, subpel- 

 lucid, with a white villosity at the base. 



Pileus 3 to 6 lines broad and high ; stem about 1 in. long. 



Among mosses and ferns in marshes. Karner. Sept. 



This species is closely related to A. acicula of which it may 

 possibly be a large form, but inasmuch as it ditiers not only in size 

 but also in its longer and more conical or campanulate pileus and in 

 its differently colored lamella? it seems best to keep it distinct. 



Agaricus spathulatus. Pers. 

 Ground. Sandlake. June. 



Agaricus (Pleurotiis) atropellitus. 



Decaying wood and bark both of fronduse and acerose trees. 

 Maryland. Helderberg and Adirondack mountains. June to Oct. 



Agaricus (Clitopilus) pascuensis, n. q). 

 Pileus fleshy, compact, centrally depressed, glabrous, ]ialc-alutac- 

 eous, the cujticle of the disk cracking into minute areas; lainelho 

 rather narrow, close, decurrent, whitish, becoming flesh-colored ; stem 

 short, equal or tapering downward, solid, glabrous, coloreil like the 

 pileus ; s])ores subelliptical, pale-incarnate, .0003 to .0004 in. long, 

 .0002 to .00025 broad.
