4ii PARKIN: FUNGI PARASITIC 



The dirk p us" ill- rred on the lower surface of leaves of 



'/ mium lancenlatum and were not at all abundant — never 

 more than two or throe on a leaf and those bearing them 

 >e. The evidence for their position on a scale was 

 not oonclof • 



Two or three months later while on a visit to Horton 

 Plains. I found a few similar pustules on the upper surface 

 of leaves of Calophyttum Walkeri. In this case there was 

 no doubt of the fungus being on a scale-insect, as sufficient 

 remains were there to allow Mr. Green to identify it as a 

 species of Lecaninm. 



A third example, probably identical with the above, was 

 sent to Mr. Green from .lava. It was on a Lecomium, sp., on 

 the leaf of Jambosa aqua. 



Description of the Fungus. 

 Th<- dark brown or black pustules (stromata) are hemis- 

 pherical in shape with an even surface and with usually a 

 swollen basal collar. The colour of the interior is orange, 

 only the exterior is black. They measure from 1 -J. nun. 

 in height. 

 Some, apparently the younger ones, were covered (especially 

 upper part) with a gray bloom, easily rubbed off reveal- 

 ing tin- shiny black surface beneath. This bloom is composed 



of COnidia, In fact m-arly the whole surface of such a 

 stroma la covered with a con id la-bearing hymenium, similar 



to what linos the pyenidia of ^schersonia. The oonidia 



mble those of this genua being fusiform, hyaline, and
