 14 in. across when exjDanded ; stem 8 in. long by 2 in. thick ; 

 gills 1^ in. broad; weight 2^ lbs: spores normal size. 



Pileus 2 in. or more broad, at first entirely enclosed in a

 white, silky with yellowish-white narrow silky scales, and 

 marked frequently with a few dark blotches, the remains of 

 the volva; flesh whitish, firm, elastic, margin involute. Gills 

 numerous, close, ventricose, quite free, not reaching to the 

 margin, at first white then rose-coloured with a tinge of
