CANE FUNGI OF SANTO DOMINGO. 



Because of the close proximity of Santo Domingo and the fact 

 that cane for milling is brought from there in large quantities by 

 one of the Central companies, there has always been considerable 

 interest taken in the cane fungi of this Island and the possibility 

 of introducing new diseases to Porto Rico through this channel. 

 Because of this threatening danger the senior author visited Santo 

 Domingo some years ago making special search for diseases not al- 

 ready occurring Porto Rico and at the same time collecting all cane 

 fungi found. A report of this trip was published at the time (49) 

 and included mention of some five fungi causing the common diseases 

 noted. Since that time determinations have been made of the other 

 fungi collected and a complete list is here given with the localities 

 in which found. It will be noted that no fungi are contained in 

 the list not already reported as occurring in Porto Rico. All collec- 

 tions were made by Mr. Johnston, between April 4 and 20, 1913.
