Abstract

The genus Mycosphaerella Johanson contains many pathogens capable of causing a severe impact on
the growth of susceptible eucalypt species. The lack of knowledge about which species are present in
Tasmania and their potential risk to the plantation industry prompted this study into the Mycosphaerella
species occurring on Eucalyptus globulus and Eucalyptus nitens plantations in Tasmania. A
total of 36 plantation and ®ve road verge sites of E. globulus and E. nitens were sampled. Five Mycosphaerella
species and three species from associated anamorph genera were isolated and identi®ed in
Tasmania; Mycosphaerella nubilosa, Mycosphaerella cryptica, Mycosphaerella tasmaniensis, Mycosphaerella
grandis, Mycosphaerella vespa, Coniothyrium ovatum, Sonderhenia eucalypticola and Sonderhenia
eucalyptorum. The most frequently isolated species with the highest incidence and severity
of infection were M. cryptica and M. nubilosa. These two species appear to have the greatest potential
to damage juvenile eucalypt plantations in Tasmania. A link between Mycosphaerella vespa and
Coniothyrium ovatum is described for the ®rst time.
