Lichens are highly successful obligate mutualistic symbioses between fungi and photosynthetic green algae and cyanobacteria that live within their tissues. Bright orange-colored species of the fungi in the group named Teloschistales are among the most noticeable lichens worldwide. This recently redefined group of fungi includes nearly 2,000 described species that live in wide variety of habitats, including surfaces of man-made substrates. This will be the first global phylogenetic study of these brightly colored organisms. The results of this study will lead to a better understanding of the diversity of these fungi, and will likely result in the description of new families and the re-definition of most genera. This study will also be an experimental test of a novel method of finding genetic markers that can be used to study patterns of evolution in fungi and other organisms. This study will also demonstrate the importance of studying the evolution of genes involved in reproduction in organisms living in symbiotic systems.In addition to the training of one female postdoctoral researcher and one female Ph.D. student, a workshop will be organized during year three of this proposed project to develop a worldwide consensus among all leading experts on a new system of classification for these fungi. This new classification, which will be co-authored by all workshop participants, will be a long-lasting contribution of this project to fungal biology.

地衣是生活在组织内的真菌和光合绿藻类和蓝细菌之间的非常成功的互助性共生。名为Teloschistales的真菌的鲜橙色物种是全球最引人注目的地衣之一。最近重新定义的一组真菌包括近2,000种生活在各种栖息地的物种，包括人造底物的表面。这将是对这些鲜艳的生物的首次全球系统发育研究。这项研究的结果将使人们更好地了解这些真菌的多样性，并可能导致对新家庭的描述和大多数属的重新定义。 这项研究还将是一种实验测试，以发现一种新方法，该方法可用于研究真菌和其他生物的进化模式。 这项研究还将证明研究生活在共生系统中的生物中繁殖的基因演变的重要性。在培训一名女性博士后研究员和一位女性博士学位的培训中。学生，将在该拟议项目的第三年组织研讨会，以在所有领先的专家中建立全球共识，以解决这些真菌的新分类系统。这个新的分类将由所有研讨会参与者共着，将是该项目对真菌生物学的持久贡献。
