ABSTRACT = {While studying the etiology of onion diseases in southern Argentina, a coelomycetous fungus was found associated with diverse disease expressions. They included the typical smudge symptoms in white onion bulbs in local markets as well as field infections on yellow- and red-coloured cultivars, with severe infections on transplants in the seed-bed. The fungus was isolated and identified as <i>Colletotrichum circinans</i> on the basis of its morphological, morphometric, biological and pathological characteristics. Two isolates, obtained from white bulbs and from transplants, were inoculated on bulbs of white and yellow-coloured cultivars and produced the typical smudge symptoms on the outer scales. Koch´s postulates were fulfilled by re-isolating the inoculated fungus. This is the first record of <i>C. circinans</i> in southern Argentina and the first observation of the disease in the field in this country.},
