Subgenus Hyfholoma. 

 Pileus fleshy, at first incurved; the veil rudimentarj' and 

 adherent to the margin. Annuhis none. 



38. Agaricus sublateritius, Schceff. 



Pileus yellow, the disk reddish brown, fleshy, convex, then 

 expanded, at first silky then glabrous; lamellae not broad, 

 adnate, yellowish, olive-green, then purple or purplish brown; 

 stipe yellow, equal, sometimes silky or fibrillose and brown at 

 the base, hollow or stuffed. 



Height 2 '-6'. Pileus 2 '-5'. Spores .004 x.006 mm. 



One of our most common autumnal species', in protected 

 situations fruiting through the winter. Found at the base of 

 stumps, in crowded, ccespitose tufts, but sometimes isolated, 

 when the maximum size is attained. A spore-stained band 

 sometimes marks the place of the annulus. The changing 

 lamellae are very characteristic, and all the tints named can 

 easily be found in a single tuft. A. perplexus, of the Twenty- 

 third New York Report, seems to be the same thing. 



Inedible, the taste by no means enticing. 



39. Agaricus lachrvmabundus, JFr. 



Pileus pale brown, scaly, the scales innate and darker, 

 fleshy, convex; lamella; adnate, crowded, purplish -brown, 

 generally edged with minute water-drops like so many beads 

 of white; stipe white, fibrillose-scaly, hollow. 



Height 3'-5'. Pileus 2'-^'. Spores elliptic, .oosx.oopmm. 



A stout, handsome and well-marked species, easily recog- 

 nized by the characters cited. Found in autumn on the 

 ground and on rotten trunks, commonly m clusters, gre- 

 garious or ccespitose. 



A tough, persistent species, the odor and taste alike dis- 

 agreeable. Not common. 



40. Agaricus velutinus, Pers. 



Pileus somewhat fleshy, slaty-brown in color, campanulate- 

 expanded, umbonate, at first tomentose with appressed fibrils,
