It appears to be a fairly coiuinon form on Lecanium in the 

 East. The Aschersonia stage is recorded by Parkin in his 

 paper on "Fungi parasitic on Scale Insects" (Ann. Perad., 

 Vol. III., pp. 11-82) under the heading " B. — Forms Avith rich 

 brown unflattened stromata without paraphyses " (p. 38), 

 and again under the heading " A Fungus Avitli Aschersonia- 

 like stromata, but black" (p. 39). Parkin states that the 

 conidia are 4 to 5 ^ broad, but an examination of his specimens 

 proves that they are only 1 • 5 to 2 /* broad. He records the 

 Hypocrella stage on pages 29 and 30, the orange-coloured form 

 as No. 1, and the black form as No. 3, but the length of the 

 ascus is said to be 103 M, whereas his specimens show that it 

 is 170 to 180 /* ; there are asci 110 A* in length, but they are 

 immature. Parkin's Hypocrella No. 2 was on Ghionaspis : it 

 was immature, and it is not included among his material at 

 Peradeniya. 



The forms recorded by Parkin, and Berkeley and Broome, 

 which are now in the Peradeniya herbarium and have been 

 re-examined, occur on — 



Lecanium expansum, on leaves of Schumacheria alnifolia 

 (Ceylon). 



Lecanium sp., on leaves of Oelonium lanceolatum (Ceylon). 



Lecanium psidii, on leaves and stems of Myristica moschata 

 (Ceylon). 



Lecanium hemisphcericum var. coffece, on tea leaf and stem 

 (Assam). 



Lecanium sp., on tea leaf and stem. (Kurseong and 

 Darjeehng). 



Lecanium sp., on Calophyllum Walker i (Ceylon). 



Lecanium sp., on Jamhosa aqua (Java). 



Lecanium, nigrum, on Smilax sp. (Ceylon). 



To these are to be added the following recent examples on — 



Lecanium, nigrum, on leaves and stems of Hevea hrasiliensis 

 (Ceylon). 



Lecanium hemisphcericum, on Schizoea digitata (Ceylon). 



Lecanium sp., on leaf of Garcinia sp. (Ceylon). 



Lecanium irmrsupiale , on an undetermined leaf (India). 



Lecanium tessellatum, on Litsea zeylanica (Ceylon). 



Eriochiton thece, on tea leaf and stem (Assam).
