Molecular phylogenetic analysis, morphology and pathogenicity to citrus fruit were used to study two isolates of Elsinoë australis associated with scab-like symptoms on a fruit of Citrus australasica (finger lime) and Simmondsia chinensis (jojoba) in Australia. In addition to being associated with finger lime, the isolate from finger lime could cause scab symptoms on C. × aurantium cv. Murcott tangor in pathogenicity tests, but could not cause scab symptoms on the other orange, mandarin, lemon or grapefruit tested. Pathogenicity tests also support previous studies showing the isolate from jojoba could not produce symptoms on fruit of C. natsudaidai. Based on the findings of this study, two novel pathotypes of E. australis are designated from Australia; namely the Finger Lime (FL) pathotype associated with finger lime, and the Jojoba Black Scab (JBS) pathotype associated with black scab of jojoba. The significance of these novel E. australis pathotypes on market access and biosecurity issues for citrus are briefly discussed.
