posted on 2023-05-16, 12:19 authored by Yuan, ZQ, Wardlaw, T, Caroline MohammedCaroline MohammedA mitosporic fungus with small conidia was frequently isolated from blighted shoots and leaves of young plantation trees and nursery seedlings of Eucalyptus nitens and E. globulus in Tasmania. Lesions on these shoots and leaves are purple to light brown, becoming necrotic with well-defined margins. The fungus is characterized by having acervular conidiomata, cylindrical to lageniform monophialidic conidiogenous cells, and spheroid to pyriform conidia that are hyaline, aseptate, and often produced in chains. The morphological characteristics fit the published description for the genus Gloeosporidina. This is the first record of a member in the genus from Australia and the first time a Gloeosporidina species has been found on eucalypts.
