on the margin, grayish brown or pale vandyke brown, the cuticular 

 surface often cracking and separating in places but remaining on 

 the disk and sometimes on the margin, flesh white; lamellae nar- 

 row, close, emarginate, adnexed, decurrent with a tooth, crenu- 

 late on the edge, white becoming brownish gray ; stem equal, solid, 

 silky fibrillose, white or whitish without and within; spores yel- 

 lowish brown (raw umber), elliptic, even, .0003-.0004 of an inch 

 long, .0002-.00024 broad; cystidia flask shape, .002-.0024 of an 

 inch long. 



Pileus 1-2 inches broad; stem 1-2 inches long, 2-3 lines thick. 

 Among fallen leaves in woods. Lake Pleasant. August. 



The surface of the pileus cracks longitudinally and therefore 

 the species belongs to the section Rimosi. The peeling and disap- 

 pearance of parts of the cuticle suggest the specific name. A 

 slight whitish webby veil is present in the young plant. 



Inocybe fallax n. sp. 



PLATE 0^ FIG. 20-24 



Pileus thin, campanulate or convex, umbonate, obscurely fibril- 

 lose, sometimes minutely and obscurely squamulose, whitish or buff 

 white, somewhat shining, the margin decurved or incurved, often 

 splitting; lamellae thin, close, rounded behind, slightly adnexed, 

 pallid when young, becoming rusty brownish when old; stem 

 long, equal, hollow, flexuous, minutely pruinose, mealy, whitish; 

 spores angular, slightly nodulose, .0003-.0004 of an inch long, 

 .00024-.0003 broad ; cystidia .0016.002 of an inch long, .0006-.0007 

 broad, oblong elliptic. 



Pileus 1-2 inches broad; stem 2-3 inches long, 2-4 lines thick. 

 Among fallen leaves in woods. Lake Pleasant. August. 



This species might easily be taken for a large form of I. 

 geophylla, but an examination of its spores shows it to be 

 distinct. Its cystidia are short and broad. 



Inocybe serotina n. sp. 



Pileus fleshy, firm, varying from campanulate to nearly plane, 



fibrillose toward the margin, white, sometimes tinged with yellow 



or brownish yellow, flesh white; lamellae close, rounded behind, 



nearly free, subventricose in fully expanded specimens, whitish
