TL;DR: The phylogenies confirm that ascus morphology cannot be applied consistently to shape the classification of lichen-forming fungi and conclude that a phylogenetic synthesis for a chosen taxonomic group should include a comprehensive assessment of phylogenetic confidence based on multiple estimates using different methods and on a progressive taxon sampling with an increasing number of taxa, even if it involves an increasing amount of missing data.

TL;DR: A multigene phylogenetic synthesis of the Lecanoromycetes based on 642 newly generated and 3329 publicly available sequences revealing relatively stable relationships for many families and orders is provided.

TL;DR: The Extended Specimen Network is a Strategy to Enhance US Biodiversity Collections, Promote Research and Education and to enhance research and Education.

TL;DR: The phylogenetic hypothesis supports the independent origin of lichenicolous fungi associated with climatic shifts at the Oligocene-Miocene boundary and provides novel insight into evolutionary relationships in this large and diverse family of Lichen-forming ascomycetes.

TL;DR: In this paper, the impacts of climate change on high-elevation, endemic lichens in the southern Appalachians, a global diversity hotspot for many groups of organisms, including lichens, were investigated.
