DIRECTIONS FOR USING KEYS. 



Let us suppose that the beginner finds a 

 mushroom and wishes to name it. He has 

 learned its component parts. He has remarked 

 the names of the classes into which mushrooms 

 are divided. How then shall he make use of 

 the Keys ? We will imagine that he has found 

 a Cantharellus. The cap is yellow color, so let 

 him turn to the list of fungi described under 

 the section " Yellow and Orange," and see if 

 it agrees in appearance with anyone of these. 

 (It is necessary before consulting a key to 

 find the color of the spores. This is done 

 by cutting off the cap, and placing it, gills 

 downward, on paper, and leaving it there for 

 two or three hours. Having followed these 

 directions in this case it will have been seen 

 that the spores are white.) 



After consulting the list of "Yellow and 

 Orange" he will find that the first one men- 

 tioned is Cantharellus cibarius, the Chantarelle.
