of his formerly published and reported species without much refer- 

 ence to the considerable mass of undetermined material of those 

 groups which was stored away in bundles. This is well illustrated 

 by Kaufifman's critical study of Doctor Peck's material of the genus 

 Inocybe^. 



In his notebooks Doctor Peck described under tentative names 

 a very large number of fungi which his critical judgment did not 

 permit him to publish for one reason or another. Without doubt 

 many of these are valid as well as unpublished species, as indicated by 

 MurrilF in the case of S t r o p h a r i a c a m p e s t r i s Peck, and 

 Stropharia rugoso-annulata Farlow ; Peck. Since the 

 notes were made almost without exception from fresh material they 

 possess a considerable value to the later students of those groups 

 represented. In addition, his notes upon many well-known as well 

 as little known species, made from fresh material and never pub- 

 Hshed, may undoubtedly be of assistance to other investigators. 



In order that these voluminous notes, occupying some thirty large 

 notebooks, might be available for reference, there has been prepared 

 an index, which has been typed with two carbon copies. One of 

 the copies has been placed in the office of pathological collections 

 at Washington, and the other in the mycological laboratory of the 

 New York Botanical Garden. From the original index Dr Howard 

 A. Kelly of Baltimore, whose interest in mycological research is 

 well known, has had six additional copies prepared which were dis- 

 tributed as follows : one to Harvard University, one to the Missouri 

 Botanical Garden, one to the University of Michigan, one to Cornell 

 University, one for his personal library, and one to Professor 

 Beardslee. 



Investigators working at Albany may have reference to these 

 notes through the index. Those working at a distance and con- 

 sulting the copies at the institutions mentioned, may secure upon 

 appUcation a transcript of such items as are desired. Unless the 

 material to which the notes refer is quite ample, however, it is a 

 rule of the New York State Museum not to lend material, especially 

 type specimens. 



Doctor Peck's notebooks covering a period from 1868 to 1913, 

 have been numbered as follows : 



1 New York State Mus. Bui. 233-34: 43-6o. 1921. 



2 Mycologia 14: 136, 139. 1022.
