Meanwhile Gaumann had published in Switzerland his " Vergleichende 

 Morphologic der Pilze " in 1926. Making use of recent advances in our 

 knowledge of the cytology of the Fungi he was able to show relationships 

 between Fungi hitherto widely separated in systematic position. As a 

 result he considerably altered the method of classification. In 1928 Dodge 

 translated and extensively altered Gaumann's original work in an attempt 

 to make the work more readily available to American readers. This book, 

 " Comparative Morphology of Fungi", is now (1951) regarded as the 

 standard American work and we give below an outline of the classification 

 used therein.
