of Huniaeao,. and the specimens were- determined by Klotzsch, who 

 listed them in Linntva (50). ^ It was not until 1884-87 that farther 

 collections were made, during which period P. Sintenis visited va- 

 rious parts of the Island. The fungi gathei-ed by him were worked 

 over by J. Bresadola, P. Hennings, and P. ^Magnus and their deter- 

 minations were publislied in 1893 (76). A recapitulation of these 

 two lists was given by Heller (35) in 1900. 



The work of these two collectors was a])i3arently all that was ac- 

 complished during the time of Spanish sovereignty. As far as knoM'n 

 to the writer the late I)i'. Stahl made no mention of fungi in his writ- 

 ings, althougli he did serve at one time on a royal commission ap- 

 pointed to study a cane disease. 



Since the change in government in 1898 the collecting and study- 

 ing of tlie fungi li;is been carried on by workers connected with tlie 

 experiment stations, and by a number of northern botanists who 

 have made collecting trips to the Island. 



Since the yeai- 1903, the reports of the Federal Experiment Sta- 

 tion at Mayagiiez have contained references to various fungi from 

 an economic standpoint. These have included notes by Barrett (6-9) 

 on diseases of oranges, tjautia, vegetables and other crops, by Hen- 

 ricksen (36) on diseases of vegetables, and by Fawcett (22-32) on 

 diseases of eoffoe, sugar cane, citrus. l)anana, cacao, and vanilla. 

 The latter has in addition to his annual reports as pathologist of 

 the Station pid)]islied a ])ulletin on coffee diseases (31), and a short 

 article on PcUioHlaria (28) . Some of the entomogenous fungi have 

 been mentioned ])y Tower (100). A banana disease due to a vascu- 

 lar fungus parasite has been studied by Prandes HO. ^^) of the same 

 institution. 



Work on the fungi as disease-producing agents of sugar cane was 

 immediately taken uj) at Ihe experiment station of the Sugar Pro- 

 ducers' Association following its estal)lislimeut iu 1910. Keports of 

 this work were issued from time to time as ])ublications of the sta 

 tion (38-48). Following the transl'ei- of Ihe institution to the Insu- 

 lar Goverinuent, studies were begun on diseases of other crops in 

 addition to the sugai'-cane investigations. Results obtained have been 

 issued in the various station publications ])repared by the present 

 pathologist (84-96). These have been concerned with diseases of 

 citrus, vegetables, and minor economic plants. 



The first of the American botanists to collect fungi, at least fn 

 any great extent, was A. A. Hellei-, who together with Mrs. Heller
