The thirty-four Subgenera o£ Agaricus are lUvidcd into five scries, 

 to eacli of which a table is here assigned. These series are ai'- 

 ranged according to the colour of the Spores. Table I. presents 

 types of the Subgenera in which the spores are white ; Table 11. 

 shows those in which the spores are pink, salmon, or rosy ; Table 

 III. shows those in which the spores are buff, clay-coloured, dull 

 or bright brown ; Table IV. shows those in which the spoi'cs arc 

 purple, brown or black with a purple tinge ; Table V. shows those 

 in which the spores are dead black. 



Each series is further arranged in three groups, founded on tlie 

 following distinctions : — 



In Group 1, the Hymenophore is distinct from the fleshy stem. 



In Group 2, the Hymenophore is confluent and homogeneous 

 with the fleshy stem. 



In Group 3, the Hymenophore is confluent with, but hetero- 

 geneous fi^om, the cartilaginous stem. 



The three groups are spaced out with blanks, and are similai-ly 

 arranged in each of the five tables, so as to show the corresponding 

 subgenera in the several series. Thus Amanita will be seen ti> 

 correspond with Volvaria, but analogues to tliese subgenera are 

 not found in the remaining series. 



The figures are drawn from sections of the fungi, in most nisos 

 reduced below the natural size. The spores shown are from highly 

 magnified specimens. 



Lettering has been introduced to aid students in understanding 

 certain structural points. 



The tables are arranged according to the construefion of .Mr. 

 Worthington G. Smith, and the di-awings ai-e af(cr his ni-iginiil 

 design.s, as adopted by Mr. M. C. Cooke. 



N.B. — Beginners are warned to dil1x>rentiate first between iho 

 genus Agaricus and the other genera of the order Agaricini.
