NOTES AND BRIEF ARTICLES 



[Unsigned notes are by the editor] 



Dr. Murrill visited the State Museum at Albany early in Feb- 

 ruary to study types of certain species of dark-spored gill-fungi in 

 collections made by the late Dr. Peck. 



Prof. H. M. Fitzpatrick, of Cornell University, spent several 

 days at the Garden late in January examining specimens of an 

 interesting group of Pyrenomycetes, which he is monographing. 

 He also visited the mycological herbaria at Washington, Phila- 

 delphia, and Boston. 



Mr. Harold E. Parks, whose articles on underground fungi have 

 been read with so much interest, has been appointed technical 

 assistant and collector in the Department of Botany at the Uni- 

 versity of California. His address is no longer San Jose, but 

 Berkeley. 



Supplementary lists of species of smuts and rusts occurring in 

 Indiana, prepared by H. S. Jackson, were published in the Pro- 

 ceedings of the Indiana Academy of Sciences for 1920. 



Cryptogamic diseases of cacao and of cocoanut, over 20 in num- 

 ber, are discussed at length by R. Averna-Sacca in the Agricultural 

 Bulletin of San Paulo for 1920. Forty-one figures accompany the 

 140 pages of text. 



An illustrated article by C. E. Chidsey in the Scientific American 

 Monthly for November, 1920, attempts to explain the formation 

 of knots and boles on forest trees. This article might be interest- 

 ing in connection with some of the recent experiments on plant 

 cankers.
