As Ag. liivlatii.s Fries, has precedence of this species, the name adopted by 

 the Rev. M. J. Berkeley must be given up, and we therefore substitute 

 another. According to custom this would be Ag. Berkeleyi^ if that name had 

 not already been adopted for an Indian species.

Pileus somewhat fleshy, nearly plane, unequal, sub-umbonate, 

 smooth ; stem minutely fistulose, tough, pulverulent, becoming 

 pallid, root strigose or fibrillose ; gills free, narrow, much 

 crowded, becoming pallid. — Fr. Epicr. p. 89. Buxh. i. t. 57, /. 2.
