It was long a reproach to mycologists in this country that 
there were few or no good English books on fungi. Students had 
to be referred to works in other languages or to translations of 
books which were often of relatively ancient date. The author 
has now removed this reproach, and all students of mycology 
will be grateful to her for this presentation of an eminently 
readable account of some of the most important groups of fungi. 
The book will be particularly welcome to university botanical 
students because it deals in a specially clear manner with the 
classification of the forms included in the Ascomycetes, Ustila- 
ginales, and Uredinales. The book is.written from the morpho- 
logical standpoint with a strong cytological orientation, for 
although Chapter I deals with fungal saprophytism, parasitism, 
symbiosis, and with the reactions of fungi to stimuli, only the 
fringe of these interesting topics is touched upon. A clear idea 
of the morphology of the fungi, such as this book conveys, is 
essential to anyone who wishes to follow one of the many 
avenues of investigation now available in mycology, and it
