Detection of the Togninia Teleomorph of Phaeoacremonium aleophilum in Australia

Abstract

Moist incubation of grapevine wood infected with both Phaeoacremonium aleophilum and Phaeomoniella
chlamydospora yielded an ascomycete referable to the genus Togninia (Ascomycota, Calosphaeriales). Single ascospore
cultures were morphologically identical to Pm. aleophilum. The rDNA ITS sequence of single ascospore
isolates was identical to published sequences for the majority of Pm. aleophilum isolates. Comparison with the morphology
of other wood staining Togninia species confirms that the teleomorph of Pm. aleophilum is Togninia minima.
