p. 475—4TS. 
Thyridaria tarda is the cause of die-back. It is a wound parasite, and 
the disease is caused by the fungus when it is in its Diplodia stage. 
The Diplodia condition is capable of reproducing itself and passes on 
the dead parts into the ascigerous (Thyridaria ) condition some time 
alter they are dead.

Dept. Agr. Fed. .Malay States Bui. 9, 28 p., illus. 
The fungus is a wound parasite and the disease is caused by the 
Diplodia stage. The ascigerous form is Thyridaria tarda, of which 
the two pycriidial forms, Diplodia and Cytospora, are stages.

Malay States, v. 10, p. 110-114, illus. 
" Clamp-connexions can be frequently found in the mycelium on the 
leaves . . . From the presence of these organs the fungus is con-

this nature; one might expect the fungus to belong either to the 
genus Hypochnus or to the genus Corticium.''
