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, velvety ; setulas cylindrical- 

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

 microns.

HymenochcBte sp., a fungus which attacks cacao, Castilloa, 

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

 the genus HymenochcBte. 



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 

 hyphse. 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.

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

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