Species of eucalypts are commonly cultivated for solid wood and pulp products. The expansion of commercially managed eucalypt plantations has chiefly been driven by their rapid growth and suitability for propagation across a very wide variety of sites and climatic conditions. Infection of foliar fungal pathogens of eucalypts is resulting in increasingly negative impacts on commercial forest industries globally. To assist in evaluating this threat, the present study provides a global perspective on foliar pathogens of eucalypts. We treat 110 different genera including species associated with foliar disease symptoms of these hosts. The vast majority of these fungi have been grown in axenic culture, and subjected to DNA sequence analysis, resolving their phylogeny. During the course of this study several new genera and species were encountered, and these are described. New genera include: ( on Australia), ( on Australia), ( on , South Africa), ( on , Australia), ( on , Australia), (incl. ., on , Australia), and ( on , Australia). New species include (all from Australia): on on on , on , on on , on , on , on sp., on sp., on , on , on and on . A new name is also proposed for as on , Uruguay. Although many of these genera and species are commonly associated with disease problems, several appear to be opportunists developing on stressed or dying tissues. For the majority of these fungi, pathogenicity remains to be determined. This represents an important goal for forest pathologists and biologists in the future. Consequently, this study will promote renewed interest in foliar pathogens of eucalypts, leading to investigations that will provide an improved understanding of the biology of these fungi.
桉树种通常因其实木和纸浆产品而被广泛种植。商业经营的桉树种植园的扩张主要是由于它们生长迅速，并且适合在各种各样的地点和气候条件下繁殖。桉树叶片真菌病原体的感染正给全球商业林业带来越来越大的负面影响。为了帮助评估这一威胁，本研究提供了关于桉树叶片病原体的全球视角。我们研究了110个不同的属，包括与这些寄主叶片病害症状相关的物种。这些真菌中的绝大多数已在无菌培养中生长，并进行了DNA序列分析，以确定它们的系统发育。在这项研究过程中，发现了几个新属和新物种，并对它们进行了描述。新属包括：（在澳大利亚）、（在澳大利亚）、（在，南非）、（在，澳大利亚）、（在，澳大利亚）、（包括，在，澳大利亚）以及（在，澳大利亚）。新物种包括（均来自澳大利亚）：在、在、在、在、在、在、在、在、在、在、在、在和在。还为（在乌拉圭）提出了一个新名称，即。尽管这些属和物种中的许多通常与病害问题有关，但有几个似乎是在受胁迫或垂死组织上生长的机会性病菌。对于这些真菌中的大多数，其致病性仍有待确定。这是未来森林病理学家和生物学家的一个重要目标。因此，这项研究将激发对桉树叶片病原体的新兴趣，从而引发相关研究，以便更好地了解这些真菌的生物学特性。
