THE FUNGUS FLORA OF HEVEA BRASILIENSIS. 



A little while a.iio an enquirv was received asking- what were 

 the fungus di.seases of Jlerea brn.--hHensis. On consultinji' the litera- 

 ture on this suhject it was ascertained that there was no recent 

 complete enumeration of the diseases that have heen found to 

 attack this tree in Malaya. Such lists have heen ]irepared for 

 other loiiiitries. as for instani'c hv Petch for the llerea in Ceylon, 

 hut the diseases are not necessai-ilv tlie same in different countries 

 -and it seemed desirable tlierefoi-e to have a list for Malaya. 



At the same time the present paper aoes further than record- 

 ing the diseases that have actually been proved and enumerates all 

 fungi, both those that are known to he iiarasitic and those that 

 are so far regarded as sajn'ophytic. wliich have heen found on 

 Hevea local 1\'. 



The im])ortance of having such a list is ablv reasoned by Pro- 

 fessor C. F. Baker in Vol. I'l, Xo. 4 of the " iQardens Bulletin," 

 in his article " Hevea versus Fungi." 



The records from which this compilation is made are the 

 works and collections of H. X. Eidley, W. J. Gallagher, K. Banc- 

 roft, A. Sharpies, W. X. C. Belgrave, R. U. Eichards, and C. F. 

 Baker. 



It is considered that additions will have to l)e made to this 

 list from time to time as further investigations produce new 

 records. 



Ridley in " The Agricultural Bulletin, Straits Settlements and 

 Federated Malay States," Vol. X, 1911, page 141, quoting M. 

 George Yernet gives on page 1 i;> "a list of all pests recorded to the 

 plant," and numerates 'i.o si)ecies of fungus, ending with the com- 

 ment, " This may seem a formidable list but it is really small 

 compared with the ])ests which attract most cultivated plants."
