Pink disease attacks many different kinds of trees and probably 
spreads from jungle plants. Has been reported from Java, southern 
India, and Ceylon. Disease attributed to Corticium calceum in the 
Federated Malay States is probably the same.

Roy. Bot. Gard., Ceylon, v. 5, p. 47-54, illus. 
It is the commonest root disease of Hevea in Ceylon, and also 
attacks many other plants. Found in southern India, Java, and 
throughout the eastern Tropics and causes some loss in plantations 
of all descriptions. Summary in Trop. Agr., v. 35, p. 180-181, 1910.

Phytophthora faberi. Description of the fungus and treatment. 
1910. Die-back of Hevea brasiliensis. In Circs, and Agr. Jour. Roy. Bot. Gard., 
Ceylon, v. 4, p. 307-321. 
Green branches are killed by Gloeosporium alborubrum. This is 
followed by Botryodiplodia elasticae, which may kill the entire tree.
