755. A. pennatus Fr. Pileus 12 mm. (}4 in.) high, and when 

 at length expanded 2.5 cent, (i in.) broad, inclining to livid then 

 white, or becoming fuscous-brick when young, somewhat mem- 

 branaceous, ovate then campanulate, not striate, but for a long 

 time and densely clothed with white plumose scales, at length naked. 

 Stem 2.5-4 cent. (\-\Yz in.) long, 2-4 mm. (1-2 lin.) thick, fistu- 

 lose, equal, villous, white-pulverulent at the apex, silvery. Gills
