Not yet reported in Michigan. It is occasionally found farther 

 south. The present known range seems to be as far north as 

 latitude 13°. This would bring it into southern Michigan where 

 no doubt it will yet be found. Its name indicates that it is the 

 emperor of its genus, and its large, showy, orange to red cap and 

 perfect volva fully justify the name. The pileus is striate and 

 glabrous; gills and stem are yellow. "The thick volva, before split- 

 ting is about the size of a hen's egg and of like shape and color." 

 It is edible, and was served to the Caesars of Rome as a delicacy 

 long ago. It approaches the deadly A. muscaria in color, except 

 that the gills of the latter are white. Avoid eating it unless inti- 

 mately acquainted with both species. It often forms large fairy 

 rings.
