“ thread-blight” of tea, Stilbum nanuw, Massee, in Southern India 
and Ceylon. A “ leaf-blight ” of coffee in Porto Rico in 1904 has been 
attributed to an unidentified species of Scierotitint. A thread-blight 
of cacao was described from the West Indies in 1906. And recently 
a disease of pomaceous fruits known as “ liypochnose ” has been re- 
ported in North Carolina, U.S.A., and has been attributed to Hypoclmm 
ochroleucus, Noack. 
lndentification of the Fungus. 
Hitherto it has not been possible to identify the fungus on Hevea 
and camphor owing to the absence of spore-bearing organs, although 
a number of specimens have been carefully examined. 
Such an occurrence is not unusual in fungi of this nature; the 
“ thread-blight ” of tea and “hypochnose” of pomaceous fruits were 
long known before any fruiting organs were found, while the fungi 
causing the “ thread-blight " on cacao and the leaf-blight of coffee 
have yet not been identified. 
Clamp-connexions can be frequently found in the mycelium on, 
the leaves; they occur less frequently in the strands on the twigs. 
From the presence of these organs the fungus is concluded to be 
a Basidiomycete. From what is known of mycelium of ‘‘ u s • , 
one might expect the fungus to belong either to the gem - - P 
or to the genus Corticium. 
Treatment. 
The means by which the disease is spread necessitates the 
sanitation of diseased areas. All fallen leaves and twigs under 
affected trees should be scraped or gathered into heaps am l b 
The heaps should be small in order to avoid scorching of the 
rounding trees. 
The diseased trees may be cured by pruning the affected parts. 
The damage done by the fungus is confined to branches, and 
Threads are seldom met with on the old patts o < S ‘ , ’ the 
it is only necessary to remove those parts which actually bear the 
fungus, so that, providing the dtease is observed ^ sbould be
