The classification for the genera of Agaricacese discussed in this 

 bulletin is based upon the color of the spores. It is generally a com- 

 paratively easy matter to form an opinion regarding the color of the 

 spores, but if any difficulty is experienced a spore print may be made. 

 The process is very simple, and the results are quite satisfactory. 

 The stem is removed from the specimen from which a print is desired 

 and the cap placed face down on a piece of paper of contrasting color, 

 covering it with a tumbler. When the spores are mature they will 

 fall in radiating fines on the paper. If a permanent spore print is 

 desired, an alcoholic spray of white shellac may be employed. This 

 is prepared by making a saturated solution of white shellac and then 

 diluting it 50 per cent with alcohol.
