Abstract:
According to the past reports,
Septoria mortarlensis Penz.et Sacc.was the only species which cause the leaf purple spot blotch of
Eucalyptus spp.in China.Examination of the fungus on the specimens which were collected by the author on
Eucalyplus camaldulensis and
E.robasta in middle and west-stern Yunnan shows that it differs from
Septoria spp.in several respects.The conidium development is holoblastic-annellidic,the conidiophores are annellop-hores with 1-3 ridges.The conidia are not hyaline,but brownish.The wall of conidia is minutely roughened.The author offirms that it is
Phaeoseptoria eucalypti Hansf.cmed.J.Walker.The species is new to China.The main differences between
Phaeoseptoria eucalypti and
Septoria mortarlensis are discussed.
