and the more or less spherical fertile portions at the end of each branch 
also contiguous and forming a crust. Our material appears to be some- 
what larger and more robust than the form described by Hennings. The 
asci were not seen but the spores agree very well with Hennings’ de- 
scription. This may be a distinct species but in the absence of material 
of K. pechuelii for comparison I have referred it to that species. 
USTULINA Tulasne

British North Borneo, Membakut, Yates 112, October 9, 1917, on the 
base of trunks of living Hevea brasiliensis . 
This fungus was first described from material obtained on a palm in 
Java. It causes a serious disease of tea in Ceylon and is now known to 
cause a rather important disease of Hevea brasiliensis in Malaya. It has 
also been reported on Hevea brasiliensis and a number of other hosts in 
Ceylon.

British North Borneo, Membakut, Yates 1H, October 9, 1917, on living 
branches of Hevea brasiliensis; Yates 115, on branches of Annona. 
This fungus was first described from Ceylon material about 1875 and 
apparently did not attract attention again until about 1897 when it ap- 
peared on coffee in Malaya. Specimens sent to Kew were described by 
Massee as a new genus and species of fungi imperfecti which he named 
Necator decretus Massee. In 1901 Zimmermann reported the fungus on 
coffee, tea, Bixa orellana and Erythroxylon coca in Java and connected 
Necator decretus Massee with the perfect stage which he described as 
Corticium. javanicum Zimm. It was first reported from Borneo by Ridley 
in 1904 on Hevea sent from Sandakan. It is now known to occur prac- 
tically throughout the tropical regions of the orient and a recent report 
indicates its presence in Porto Rico. It causes a very serious disease 
of rubber in Malaya and Borneo and of tea in Ceylon. In the Philippines 
it causes a rather serious disease of Citrus.

British North Borneo, Tenom, Yates 105, October 17, 1917, on dead

While the specimens differ in some respects from Cesati’s description, 
as given in the Sylloge Fungorum, they agree fairly well with specimens
