The fungus takes the form of a brown, incrusted mass 

 on the trunk of the tree, and usually near the base. It 

 spreads somewhat rapidly and causes considerable injury 

 to the plant. 



Diagnosis. Broadly effuse, tenacious and subcrustaceous, 

 adnate : hymenium brown, velvet)- ; setula: cylindrical- 

 conical, 40-70 by 5-7 microns ; spores ellipsoid, 7 by 4 

 microns.

HymenocJicete sp. y a fungus which attacks cacao, Castilloa, 

 tea, cotton and other plants in Ceylon has been referred to 

 the genus Hymenochcete. 



CORTICIUM LILACINO-FUSCUM, Berk, and Curt. 



(Pink Disease of Cacao.) 



The disease does not appear to be of a serious nature ; it 

 has been reported from Dominica and St. Lucia. 



Pinkish incrustations appear on the branches of the tree ; 

 they are composed of closely packed, adpressed, fungal 

 hyphae. The hyphae may penetrate the bark and extend as 

 far inwards as the young wood ; when the branches are 

 thus affected, the bark cracks and peels off. The fungus 

 itself appears to do but little damage, since the bark is 

 easily renewed ; but it forms places of entrance for other 

 fungi, notably the cacao canker fungus. 



The fungus and the bark adhering to it should be removed 

 by means of a sharp knife and the wound should be tarred. 



Diagnosis. Hymenophore broadly effuse, entirely adnate 

 to the substratum, smooth, waxy, with a narrow white 

 margin, lilac-fuscous ; spores continuous, hyaline ; basidia 

 tetrasporous.

CORTICIUM JAVANICUM, Zimm.*

 iensis it is found on tea (up-country), plum (up-country), 

 orange (low-country) and cinchona ; in Java it occurs on 

 coffee, ramie, cacao, cinchona, nutmeg, tea, mango, 

 Castilloa elastica and other plants.
