this group of fungi will be published in Mycologia, be- 

 ginning with the number for January, 191 1. 



During the spring and summer, my studies of local 

 edible and poisonous species of gill-fungi were continued, 

 and a number of colored plates were prepared under my 

 direction for publication in future numbers of Mycologia. 

 This feature has proved very attractive and helpful to 

 students. Professor Gies and his assistants have cooper- 

 ated with me in the study of mushroom poisons, obtaining 

 valuable results by physiological and chemical methods. 

 A preliminary article on this subject appeared in the 

 November number of Mycologia. 



Continuing my investigations of woody fungi, a list of 

 the polypores found in the island of Jamaica was prepared 

 and published, and a similar list of the polypores of Mexico 

 was completed, each list containing a number of species 

 previously undescribed. 



Respectfully submitted, 



W. A. Murrill, 



Assistant Director.
