摘 要：Trapelioid fungi constitute a widespread group of mostly crust-forming lichen mycobionts that are key to understanding the early evolutionary splits in the Ostropomycetidae,the second-most species-rich subclass of lichenized *** uncertain phylogenetic resolution of the approximately 170 species referred to this group contributes to a poorly resolved backbone for the entire *** on a data set including 657 newly generated sequences from four ribosomal and four protein-coding gene loci,we tested a series of a priori and new evolutionary hypotheses regarding the relationships of trapelioid clades within *** found strong support for a monophyletic group of nine core trapelioid genera but no statistical support to reject the long-standing hypothesis that trapelioid genera are sister to Baeomycetaceae or ***,we can reject a sister group relationship to Ostropales with high *** data also shed light on several longstanding questions,recovering Anamylopsoraceae nested within Baeomycetaceae,elucidating two major monophyletic groups within trapelioids(recognized here as Trapeliaceae and Xylographaceae),and rejecting the monophyly of the genus *** transfer eleven species of the latter genus to Lambiella and describe the genus Parainoa to accommodate a previously misunderstood species of *** phylogenetic studies in Ostropomycetidae have invoked Bdivergence order^for drawing taxonomic conclusions on higher level *** data show that if backbone support is lacking,contrasting solutions may be recovered with different or added *** accordingly urge caution in concluding evolutionary relationships from unresolved phylogenies.
