Caliciopsis pleomorphasp. nov. (Ascomycota: Coryneliales) causing a severe canker disease of Eucalyptus cladocalyx and other eucalypt species in Australia

摘要

is described from a severe stem canker disease of cultivated ‘Nana’ (dwarf sugar gum) in Australia. The fungus is a pleomorphic ascomycete ( ), with pycnidial (pleurophoma-like) and hyphomycetous (phaeoacremonium-like) morphs, and differs in these respects and in ITS sequences from other spp. The fungus was also found associated with cankers on other species growing in native habitats, and was successfully inoculated under glasshouse conditions into a wide range of species on which it caused cankers of varying severity.
