perithecia with asci. These occurred sunken in the upper 

 part of the stroma. Reference has already been made to this 

 example under Hypocrella (see p. 30). 



Hence it is probable that all the above black pustules 

 belong to a species of Hypocrella. 



The conidial stroma though suggesting Aschersonia differs 

 from all hitherto described species ; if it is to be admitted, 

 then the characters of the genus will require to be somewhat 

 modified. 



By searching the up-country jungles of Ceylon more of 

 this fungus might be procured andthus permit its systematic 

 position to be definitely settled.

As was pointed out in the introduction to this paper, Zim- 

 mermann named a fungus which he found attacking the 

 green bug (Lecanium viride) on the coffee in Java, Gepha- 

 losporium Lecanii. 



The short account* he wrote about it was intended more 

 for the benefit of the Java planters than as a botanical treatise. 

 Beyond this pamphlet I have come across no further allusion 

 to such a type of fungus in connection with scale-insects. 



In Ceylon a fungus similar to this Java one has repeatedly 

 been observed by Mr. Green and myself on species of Leca- 

 nium. In fact he has been aware of it in the Island for some 

 years on the green-bug. To particularize, four separate lots 

 of material have been collected on L. viride. three lots on 

 L. hemisphcericum, and two on L. nigrum. For details see 

 Table at the end. 



The fungus shows itself to the naked eye as a white or 

 pale yellow powdery bloom around, and to some extent over 

 the scales (figs. 49 and 50). The powdery or mealy appear- 

 ance is due to innumerable conidial heads covering the
