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.

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.

 as given in the Sylloge Fungorum, they agree fairly well with specimens
