Summary A disease of the pomegranate from Lahore, has been described. The fungus causing it is a weak parasite, attacking only nursery plants through wounds. Though the infected plants are not actually killed, they become very much stunted in growth. As this species differs considerably from known species of Amphichaeta, it has been described as a new species. The spores of A. Punicae germinate readily in eight to fourteen hours and the fungus will grow on various media. The behaviour of the fungus on different media has been studied as well as the effect of different external factors on its growth. Though it is a weak parasite, its pathogenicity has been established by means of a large number of inoculation experiments.
