Abstract
In 2014, a new and serious leaf and shoot disease of unknown aetiology appeared in Eucalyptus plantations of North Sumatra, Indonesia. The disease is characterised by black necrotic spots that initially appear on young leaves and petioles, which then become scab-like as the lesions age. Infected trees respond to infection by producing shoots with small leaves that commonly appear feathered. Fruiting structures typical of most foliar pathogens are not seen, but fungal spores are evident associated with the scab-like structures using Scanning Electron Microscopy (SEM). Using culture-dependent methods, cultures resembling a species of Elsin?e were isolated from the lesions. DNA sequence comparisons for four gene regions, as well as morphological observations showed that the fungus is an undescribed species in Elsinoe, for which the name Elsinoe necatrix sp. nov. is provided. Pathogenicity trials on a Eucalyptus clone with the Elsin?e species resulted in scab-like structures similar to those observed under field conditions and the fungus was easily re-isolated from the resulting lesions. This study includes a description of the pathogen and characterization of the disease for which the name Eucalyptus scab and shoot malformation is suggested.
