We shall now pass on to a brief preliminary account of the two 

 general types. 



The Characters of the Aequi-hymeniiferous or Non-Coprinus 

 Type. These characters, which, of course, are those common to 

 all the Sub-types included in the Type, are few in number. They 

 may be described as follows : 



(1) Shape of the Gills. All fruit-bodies belonging to the 

 Aequi-hymeniiferous Type possess gills which are shaped like the 

 blade of a pen-knife. The thickest part of each gill is attached 

 to the pileus-flesh, whilst the sharp free edge is directed 

 downwards toward the earth. The sides of the gills, therefore, are 

 not parallel but are inclined to one another at an angle of a few 

 degrees. A cross-section of a gill has a wedge-shaped appearance.
