This book will be heartily welcomed by students 

 and resenrch wo'-kers in mycology and ])lant path- 

 ology. The author has recognized and attempt- 

 ed to fill the need of a complete and detailed 

 treatment of the taxonomy and morphology of 



the phycomycetes. In his classification of the 

 Phycomycetes into the eight orders, namely; 

 Chytridiales, Ancylistales, Blastocladiales, Mon- 

 oblepharidales, Saprolegniales, Peronosporales, 

 Mucorales, and Entomophthorales, the author 

 does not depart far from the older classifications. 

 Where changes are made, adequate explanation is 

 given for the reason of the change. The inclusion 

 of the Plasmodiophoracae in the Chytridiales and 

 the establishment of the order Blastocladiales are 

 examples of this. Keys are provided for all gen- 

 era. A complete discussion of the work done on 

 various species of a genus follows with citations 

 to literature. Doul)tful or excluded genera of an 

 order are treated at the end of the order. In con- 

 clusion a brief and concise survey of the various 

 views of the origin of the Phycomycetes as well 

 as Hemiascomycetous affinities is given by the 

 author. 



Technical terms are printed in boldface type 

 in the text at the point at which they are defined^ 

 or explained. Especiall\ desirable is the bibli- 

 ography found at the end of each chapter.
