2. LIST OF HOST PLANTS 



A large number of plants have been mentioned in scientific liter- 

 ature as hosts of the sporophores of Schizophyllum. It is not clear in 

 most of these references whether the specimens were found upon living 

 or dead plants. The distinction is of some importance in the consid- 

 eration of the economic aspects of the fungus. The information in the 

 following table has been obtained from publications, from the spoken 

 word of collectors whom the writer has been fortunate enough to meet, 

 from specimens in the Herbarium of the University of California, and 

 from observations in the field. Dates are given for references to 

 publications only.
