Abstract :
Microstroma sp. collected on living leaves of Celtis australis L. (Cannabaceae ) from Himachal Pradesh, India is a new host record. Symptoms of the disease on leaves appeared in the form of small, circular to irregular, white coloured spots or mouldy growth surrounded by a yellow zone. The fungus isolated was identified as Microstroma juglandis on the basis of cultural appearance and morphological characters. The pathogen was able to induce the characteristic symptoms of downy leaf spot or white mould within 14-16 days after inoculation.
