ANALYTICAL KEY. 



Figure 9. Spore-print of a Flammula. 



This key is largely based upon 

 Cooke's analytical key. Its use will 

 help to locate the plant in hand in the 

 genus to which it belongs. 



The first thing the student should 

 do is to determine the color of the 

 spore if it is not evident. This is best 

 done according to the plan described 

 on page 15. 



The plant should be fresh and ma- 

 ture. Careful attention should be 

 given to different stages of develop- 

 ment. The habit of the plant should 

 be considered ; then, as soon as the 

 color of the spores is determined, it 

 will be an easy matter to locate the 

 genus by means of the key. 



Group i Hymenomycetes. 



Mycelium floccose, giving rise to a distinct hymenium, fungus fleshy, 

 membranaceous, woody or gelatinous. Spores naked. 

 Hymenium, normally inferior 

 Hymenium with

 Hymenium on smooth 



surface, club-shaped, Clavariaceae.

shaped. Gills radiating from the 



point of attachment of the pileus with the stem, or from a lateral stem to other 



parts of the cap, simple or branched.
