The stem is white, of a soft silky surface, and easily splits 

 in shining white filaments; it is holl'iw, hut with a soft 

 silky down iii the jierfo ration. 



The curtain is white, soft, downy, and separates from the 

 rim of the pilous ; when the stem has attained but a small 

 part of its heiii'ht, it is permanent, abiding near the bottom 

 of the stem, till the decay of the plant. 



The gills are, while the plant is young, covered with a 

 carnation-coloured powder, changing black in decay, rolling 

 upwards, and dissolving in a black turbid gelly. 



The pileus at first covered with a white downy epidermis 

 which soon disappears, and the surface becomes striated, and 

 of a soft, downy, livid, carnation colour ; which colour, both 

 in the young and old plants, consists of a soft powder, which 

 at last changes black and dissolves.
