XIV, 6 Lee and Yates: Pink Disease of Citrus 659 
Corticium salmonicolor by Berkeley and Broome in 1873 ; as 
this name has undoubted priority over all other names proposed, 
it must be used for the species. 
Rant has described the disease known as “djamoer oepas” 
(poison fungus) in Java, caused by Corticium javanicum Zimm., 
and has listed one hundred forty-one wild and cultivated plant 
species attacked by the fungus; among these are Citrus sp. and 
Murraya exotica Linn. Inoculation experiments made by Rant 
proved for the first time the identity of Necator decretus Massee 
as a form of Corticium javanicum Zimm. He also published a 
number of very good figures. In 1914 Brooks and Sharpies 
gave the history of the disease in the Malay Peninsula together 
with a description of the life history of the fungus and sug- 
gestions for treatment. In 1908 von Faber reported its oc- 
currence on coffee in the Cameroons. It has also been reported 
to our knowledge from Burma, Sumatra, Borneo, southern India, 
the Caucasus, and Formosa. 
From a study of the history of the disease we find it to be 
very widely distributed throughout the eastern Tropics, and to 
occur upon a very large number of economic and wild plants. 
In 1900 the disease was practically unknown. Sharpies stated 
that in 1912 the fungus causing pink disease was known in 
only three small centers in Malaya, but by 1914 it had spread 
over practically the whole peninsula. One of us on a recent 
visit to British North Borneo found the disease to be very 
common on rubber in that country, where it would undoubtedly 
cause serious financial losses if control measures were not applied. 
CORTICIUM IN THE WEST INDIES 
A disease of cacao, lime, and other economic plants has been 
reported from the 'West Indies. It appears to have been long 
known as pink disease and was supposed to be due to a Corti- 
cium; however, it was believed to be a different species from 
that known in the East and was identified as Corticium lilacino- 
fuscum B. & C., a species described from temperate North 
America. Stockdale calls attention to the existence of a sim- 
ilar disease in the East, but does not suggest the possibility
