ACKNOWLEDGMENT 



special acknowledgment is due Mr. John A. Stevenson 

 for the preparation of this index of Mr. C. G. Lloyd's 

 Mycological Writings, and also for his years of labor 

 in indexing and systematizing Mr. Lloyd's mycologi- 

 cal collection, now permanently housed in the Bureau 

 of Plant Industry, Washington, D. C. Through the 

 efforts of Mr. Stevenson, every specimen in the collec- 

 tion is now readily accessible to students of mycology. 

 In addition, this general index will greatly facilitate 

 reference to any species mentioned in Mr. Lloyd's 

 publications.
