LEPTONIA Fr. 



In Leptonia the stem is cartilaginous, hollow or stuffed, smooth 

 and somewhat shining. The pileus is thin, umbilicate or with the 

 center darker, the surface hairy or scaly, and the margin at first 

 incurved. The gills are adnate or adnexed at first, and easily 

 separating from the stem in age. Many of the species are bright 

 colored. 



Leptonia asprella 

 Fr. This species 

 occurs on the 

 ground in woods 

 or in open grassy 

 places. The 

 plants are 3-5 cm. 

 high, the cap 2-4 

 cm. broad, and 

 the stem 2-3 mm. 

 in thickness. 



The pileus is 

 convex, then more 

 or less expanded, 

 umbilicate, rarely 

 umbonate, hair 

 brown (mouse 

 colored), with 

 dark scales on the 

 center and minute 

 scales over the 

 surface, striate. 



The gills are sinuate to adnexed. The spores are strongly 5-6 

 angled, 10-12 x 8-10 //. The stem is smooth, even, usually the same 

 color as the cap, but sometimes it is reddish brown, green, or blue. 

 Figure 142 is from plants (No. 3996, C. U. herbarium) collected 

 at Blowing Rock, N. C, during September, 1899. 



Leptonia incana Fr., is a more common species, and is character- 

 ized by an odor of mice.
