Common leaf spot of lucerne and the dawn of mycology and plant pathology in Australia.

As the number of livestock increased in the years following English colonisation of Australia in 1788, the need for nutritious fodder, including lucerne (Medicago sativa), grew. One of the first diseases found on lucerne was a leaf spot which was collected in 1879 by George Bancroft, a physician and naturalist, in a suburb of Brisbane. The Queensland Government Botanist Frederick Manson Bailey sent a specimen to the prominent English mycologists Miles Joseph Berkeley and Christopher Edmund Broome who in 1883 formally described and named the fungus Sphaerella destructiva. That fungus is now known as Pseudopeziza medicaginis , the causal agent of common leaf spot of lucerne. It was one of over 300 fungi that were included in a 1880 paper co-written by the Reverend Julian Tenison-Woods and Frederick Bailey. At that time almost all of these fungi which had been collected in Australia were identified by overseas mycologists, particularly Berkeley and Broome. It can be argued that their 1880 paper was the first significant one published in Australia which focussed on fungi. Just a decade or so later Australian scientists, in particular Daniel McAlpine, were describing new fungal taxa on their own. Among the fungi recorded in a paper published in the 1880 Proceedings of the Linnaean Society of New South Wales was Sphaerella destructiva , now Pseudopeziza medicaginis , the cause of common leaf spot of lucerne. The paper, co-authored by the naturalist Reverend Julian Tenison-Woods and the Queensland Government Botanist Frederick Manson Bailey was the first known comprehensive list of Australian fungi published by Australian residents. It is a milestone in the evolution of mycology and plant pathology studies in Australia. Photograph by H. H. Baily. [ABSTRACT FROM AUTHOR]
