AGARICACE^: 



Amanita 



in Britain with black spores, consequently this position on the fifth 

 diagram is left vacant. 



White-spored species represent the highest types and black-spored 

 species the lowest, the pink-, brown-, and purple-spored species are 

 intermediate. Amanita is the highest type of the white-spored 

 Agarics. The majority of the white-spored species are terrestrial 

 and more or less persistent, whilst the black-spored species commonly 

 grow on dung and are evanescent.
