(9) Other plant diseases. — A trial was made of the hot 

 water treatment, which is so useful in the case of oat smut, 

 against smut of bajra; the treatment proved useless. The 

 treatment of oat smut by formaline steeping was success- 

 fully demonstrated on several estates in Bihar. Investi- 

 gations into phanerogamic parasites and in particular the 

 influence of chilli saltpetre on tokra of tobacco were 

 resumed. 



IV. — Systematic Work. 



There were 505 additions to the herbarium during the 

 year under review. Of these new additions we are in- 

 debted to the Bureau of Science, Manilla, and to mycologists 

 in Berlin for 269 species. Named collections of Indian 

 Fungi were sent in exchange. Collections of fungi for 

 naming were received from, and duplicates were issued, 

 if required, to the Mycological Officers of Provincial De- 

 partments of Agriculture and the Curator, Royal Botanic 

 Gardens, Calcutta. 



The systematic study of the large collections of 

 Deuteromycetes (fungi imperfecti) in the Herbarium was 

 taken up and material obtained for a fifth part of the Fungi 

 Indies Orientalis ; the series is being published in collabora- 

 tion with H. & P. Sydow, Berlin. * At least one other part 

 will be required to finish this large group. 



A short paper was published describing the complete 

 stages of the rusts of sugarcane, figs and Oldenandia. 



V. — Miscellaneous. 



The Imperial Mycologist attended the Board of Agri- 

 culture in December and the centenary celebrations of the 

 Indian Museum in January. Assistance was given to the 

 Imperial Bacteriologist in the identification of a fungus 

 isolated from bursati tumours and in an inquiry into the 

 relationship of fungi parasitic upon fodder to certain 

 cattle diseases. In collaboration with the Imperial 

 Agricultural Bacteriologist an examination was conducted 



* This work will perforce stop during the war. — P. J. V. S.
