 A close ally of 924. Mr. C. Crossland, who has found this plant at Halifax, 

 says that the pileus is covered with white silky scales and always passes from 

 white through bright flesh-colour to black, and the annulus sometimes pro- 

 jects nearly J inch from the stem. In 924 the gills are at length ventricose, 

 but in this plant, as described by Bolton, they are linear and slightly arcuate 

 and pass from white through purple to black. In 924 the stem turns 

 black when bruised, but there is no change of colour in the Halifax plant.
