This is apparently the American for f C. t,ii,< -,-. ns Bres. of 



Europe In the lew collectionfi examined, the spores of the Dative 

 plant rarely measured over 7 micr. long, while Bresadola gives s I" 

 x .1-7 micr. for his species. When yonng this species simulates 

 Armillaria mellea, bu1 without ;i veil, later it is not easily con- 

 fused with it. The scales on the cap are often well developed.
