A TEXTBOOK OF THEORETICAL BOTANY 



dealing with the classification of certain groups of Fungi. Among these we 

 may mention the work of Patouillard, who in his " Essai Taxonomique", 

 published in 1900, developed a scheme of classification of the higher 

 Basidiomycetes based on hymenial characters. Mention may also be made 

 of Zopf, whose " Die Pilze", published in 1890, gives the best general 

 account of what was then known of the lower Phycomycetes. 



Among the general systematic descriptions of the Fungi which we 

 must consider in some detail, the first is that by Schroter (1897) in the 

 " Pflanzenfamilien " of Engler and Prantl. The outline of this classification 

 is given below:
