Abstract
Forests New SouthWales manages over 26 000 ha of young eucalypt (Eucalyptus and Corymbia) plantations, established since 1994. Forest health surveillance of these plantations was initiated in late 1995 to help protect this valuable and expanding resource. Fungi recorded during surveys from 1996 to 2005 are reported here. Over 50 species of fungi were identified, the majority being leaf spot fungi. The most commonly recorded were Quambalaria pitereka from leaves and shoots, Aulographina eucalypti, Kirramyces (=Phaeophleospora) epicoccoides and Mycosphaerella cryptica, all foliar fungi, and Botryosphaeria eucalypticola from both leaves and stems. Several species of fungi were recorded from many hosts, including A. eucalypti (18 hosts), M. cryptica (20 hosts), K. epicoccoides (14 hosts) and Botryosphaeria spp. (11 hosts). Others were restricted in their host range, such as Q. pitereka, Stigmina eucalypti, Kirramyces corymbiae prov. nom. and Lembosina corymbiae prov. nom., which were only found on species of Corymbia during these surveys. The published host range for several foliar fungi has been expanded from observations from these surveys, including for A. eucalypti, K. epicoccoides, M. cryptica, Mycosphaerella marksii, Mycosphaerella suberosa, Kirramyces eucalypti, Phaeothyriolum microthyrioides and S. eucalypti. Six new species of foliar fungi were identified during these surveys: Mycosphaerella tumulosa prov. nom., Mycosphaerella associata prov. nom., Mycosphaerella exentricum prov. nom., K. corymbiae, L. corymbiae and Lembosina eucalypticola prov. nom. Some foliar fungi were observed for the first time from New South Wales during these surveys, including M. marksii, M. suberosa, M. parva, Cryptosporiopsis eucalypti and Trimmatostroma excentricum. Tubercularia lateritia and Caliciopsis sp. spleomorpha, both stem fungi, are reported from eucalypts in New South Wales for the first time.
