1. New Species of West-American Fungi. 
The following species were mostly collected by C. F. Baker 
in California and Nevada during 1901 and 1902. Many of 
them have been issued in his distributions of West-American 
plants. I am under obligations to him for full field-notes on 
the fleshy species, thus making it possible to study and de- 
scribe them. 
The types are deposited in the herbarium of the New York 
Botanical Garden.
