readable style and should be frequently consulted by all students of 

 mycology. 



Leon H. Leonian (1888-1945), United States. Trained as a mycologist 

 under Kauffman, he was always interested in discovering the potentiali- 

 ties of living fungi. His principal contributions were made in the studj'- 

 of fungus nutrition with emphasis on the factors which are required by 

 fungi for growth and reproduction. For a bibliography of his papers see 

 Orton (1946). 



The number of living investigators who have made and are continuing 

 to make important contributions to fungus physiology is far too great to 

 list here, and for this reason they have been omitted. An idea of the 

 scope of their interests and activities may be gained from the references in 

 the following chapters.
