Pannaria leucosticta Tuckm. 

 Granitic rocks. Near Chilson lake. July. Mrs Harris. 



Lepiota adnatifolia n. sp. 

 Pileus thin except in the center, broadly convex or nearly 

 plane, minutely granulose or squamulose, isabelline, alutaceous 

 or reddish ferruginous, the margin usually appendiculate with 

 fragments of the veil, flesh white; lamellae thin, moderately 

 close, adnate, white; stem short, generally slightly thickened at 

 the base, solid when young but sometimes becoming stulBfed or 

 hollow with age, glabrous or slightly squamulose below the 

 small often evanescent ring, pallid or subrufescent; spores 

 minute, .0002-.00024 of an inch long, .00016-0002 broad. 



Pileus 1-2.5 inches broad; stem 1-1.5 inches long, 2-4 lines 

 thick. Ground under pine trees. Bolton and Hague, Warren 

 CO. September. 



The color ornamentation and size are nearly the same as in 

 L. granulosa, from which it differs in its slight veil, larger 

 spores and specially in its adnate lamellae. By this character 

 some species of Lepiota show an affinity with the genus Armil- 

 laria. Our four species having this character may be indicated 

 by the subjoined synoptic table.
