The dimensions and habit are the same as in the last species, to 

 which this is clearly related. Its lamellae also have the same 

 peculiar appearance. 



Agaricus (Naucoria) discomorfoidus, Peck. 



Pileus thin, convex or expanded, smooth, slightly viscid, reddish-brown or 

 dull chestnut ; lamellae narrow, crowded, minutely serrulate, white or pallid, 

 then brownish ; stem equal, stuffed, smooth, slightly mealy at the top, white ; 

 liesh white ; spores nucleate, .0004' x .00025'. 



Plant 2'-3' high, pileus 1—1.5' broad, stem l"-2" thick. 



Ground in woods. Croghan and Copake. September and Octo- 

 ber. 



In the dried specimens the disk has a dark discolored appearance 

 as if beginning to decay. 



Agaricus (Galera) expansns, Peck. 



Pileus subniembranaceous, expanded or depressed, viscid, plicate striate on 

 the margin, brownish-ochre, sometimes tinged with yellow and pink hues ; 

 lamellae close, ferruginous ; stem long, equal, hollow, slightly pruinose, 

 faintly striate, yellow ; spores .00045' x .00028'. 



Plant 3'-4' high, pileus 1' broad, stem 1" thick. 



Decaying wood. Sandlake.and Memphis. August. 



Agaricus (Galera) callistus, Peck. 



Pileus thin, expanded, subumbonate, smooth, viscid, striatulate on the mar- 

 gin, olivaceous or ochraceous, the umbo or disk bright chestnut color; lamel- 

 lae thin, close, ventricose, easily separating from the stem, yellowish, becoming 

 bright ferruginous ; stem equal, hollow, pruinose, yellow, spores .00035' x 

 .0002'. 



Plant l'-1.5' high, pileus 6"-10" broad, stem .5" thick. 



Exsiccated water-holes in wooded swamps. Croghan. September. 



In the dried specimens the lamellae are white on the edge and 

 the pileus has assumed a dull metallic green color. 



Agaricus (Galera) Coprinoides, Peck. 



Pileus membranaceous, soon expanded, often split on the margin, plicate- 

 sulcate to the small even disk, yellowish inclining to ochre ; lamellae close, 

 slightly rounded behind, concolorous ; stem equal, short, hollow, minutely 

 hairy-pruinose, white ; spores .00028' x .0002'. 



Plant 1' high, pileus 6" broad, stem .5" thick. 



Grassy ground. Sterling. August. 



The appearance of the pileus is suggestive of some of the smaller 

 Ooprini.
