title: New cryptic species ofTeratosphaeriaonEucalyptusin Australia.
abstract: Teratosphaeria destructansandT. viscidaare serious pathogens causing leaf, bud and shoot blight diseases ofEucalyptusplantations in the subtropics and tropics of South-East Asia (T. destructans) and North Queensland, Australia (T. viscida). During disease surveys in northern Western Australia and the Northern Territory of Australia, symptoms resembling those ofT.destructanswere observed on young and adult leaves of native and plantationEucalyptusspp. and its hybrids. Phylogenetic studies revealedTeratosphaeriaspecies associated with these symptoms are new taxonomic novelties described here asT. novaehollandiaeandT. tiwianaspp. nov. Isolates from previous records ofT. destructansrecorded in Australia were re-examined and based upon the phylogenetic evidence are reassigned to these new taxa. We conclude thatT. destructansis absent from Australia.
