HYPORHODII. 189 



The stature is wholly that of A. ceruinus, but it differs in the villous-scaly p , 

 stem, in the pileus being lacunose, at the first villous and the margin fringed 

 with hairs, and in the edge of the gills being fringed-fuliginous or marginate. 

 But these differences gradually disappear, and there are many intermediate 

 forms.
