4. The parasitism of this Vermicularia is definitely proved by repeated 
inoculations. Under moist conditions, inside bell-jars, the plants took the 
infection and showed disease symptoms in 15 days. But under drier con- 
ditions the fungus failed to infect the plants. The results of the inoculations 
confirm the field observation that the fungus made rapid progress during 
continued wet weather and high humidity. 
5. This Vermicularva on ginger inoculated on chillies and turmeric failed 
to produce any infection. 
6. The name Vermicularia Zingiberee nov. sp. is suggested, owing to (a) 
the difference in the measurements of sporodochia between Vermicularia on 
ginger, turmeric and chillies, (6) the character of the chlamydospores and (c) 
the negative results in the cross-inoculations on chillies and turmeric. = 
My thanks are due to my assistants Messrs. C. Krishnan Nair and 
C. 8. Gopalaswami Rao for their ready help. 
As this paper was completed, a Vermicularia was noticed on Knol-Khol 
(Brassica oleracea var. botrytis) and cabbage (Brassica oleracea var. cantata) 
in the Botanic Garden, Coimbatore. This fungus is under study. 
A comparative study of the Vermicularias on several hosts will form the 
subject of a separate paper.
