NOTE. 



IiT using this table the student should first 

 ascertain the color of the spores of the speci- 

 men under investigation. This will determine 

 the particular table to be applied to its fur- 

 ther examination. If, for instance, he finds its 

 spores to be white, he will know that Table I. 

 is the one to be consulted. Turning to that 

 table, he should recall the place of its growth, 

 its habitat. Now, suppose it to have been 

 found growing on a stump, he will, by 

 looking at the first column. Habitat, of 

 Table I., be informed that it must be one 

 of the four genera named in the column with 

 the heading " On Stumps." Let him then 

 examine its " gills." If he finds them to be 

 " adnate," he will be assured that it must be an 

 " Armillaria," as no other genus is shown in 

 the column as growing " on stumps " and 

 which has gills that are adnate. But to make 

 assurance doubly sure, he may proceed further
