UPON SCALE-INSECTS. 39 



1. — Ceylon example on Lecanium psidii on stems and 

 midribs of Myristica moschata (figs. 36 and 37). 



Stroma buff coloured ; pycnidial orifices scattered ; 

 pycnidia regular in shape and rather shallow. A fine speci- 

 men. 

 Indian exaiiiples. 



2. — On Lecanium hemisphwricum (var. coffeai) on tea leaf 

 and stem, Upper Assam. 



Stroma fulvous or clay-coloured ; pycnidial orifices of a 

 darker shade and scattered. 



3. — On Lecanium, sp., on tea stem, Kurseong. 



Stroma orange to brick-red, basal part yellow ; pycnidial 

 orifices irregularly arranged. 



4. —On Lecanium, sp., on tea leaf and stem, Darjeeling. 



Stroma clay-coloured with lighter tinted base. 



C. — Form with large pycnidium, only 1-3 to a stroma. 



Quite a different type of Aschersonia to the preceding was 

 found on a single occasion in the jungle, Horton Plains, 

 Ceylon, by the author. Only a few stromata were obtained. 

 The fungus was formed on a species of Aleurodes on the 

 lower surface of the leaf of Eugenia revoluta (fig. 39). 



The mature stroma possessed a hypothallus, surrounding 

 a slightly raised yellow cushion from which projected up- 

 wards a short column. This bifurcated at the top into two 

 short processes each ending in a large opening, the pycnidial 

 orifice (fig. 40). One stroma had only a terminal orifice ; 

 and another had three. The pycnidium is deep and some- 

 what lobed at the base (fig. J 1 ). 



The orifices were plugged with yellow-brown or olive- 

 green gelatinous masses of conidia. These latter, of the usual 

 Aschersonia type, measured 10 x 2/* (fig. 42). 



A Fungus with Aschersonia-like Stromata but black. 

 A distinct fungus resembling Aschersonia in shape and 

 habit, but black, was found in 1898 by Green in the jungle, 

 Pnndalu-oya, Ceylon, and handed to me for examination.
