Zq. Yuan et al., First report of Gloeosporidina sp isolated from lesions on shoots and leaves of Eucalyptus nitens and E. globulus in Australia, PLANT DIS, 84(5), 2000, pp. 510-512
A mitosporic fungus with small conidia was frequently isolated from blighte
d shoots and leaves of young plantation trees and nursery seedlings of Euca
lyptus nitens and E. globulus in Tasmania, Lesions on these shoots and leav
es 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 con
idia that are hyaline, aseptate, and often produced in chains. The morpholo
gical characteristics fit the published description for the genus Gloeospor
idina. 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.
