On this examine, we performed a complete phylogeographic evaluation of the T. mesentericum species complex, primarily based on multilocus knowledge, and including specimens from all over Europe. Phylogeny of T. mesentericum complex, primarily based on the ITS rDNA dataset. On this study, we performed an integrative taxonomic assessment of the T. mesentericum complicated, combining a multilocus phylogeographic approach with morphological analyses, and together with authentic specimens of Vittadini, and Berkeley and Broome. The taxonomy of the lineages discovered was resolved by means of an integrative method combining molecular data, morphological characters of peridium and spores, and evaluation of voucher specimens of T. mesentericum determined by Vittadini, and the sort specimens of T. bituminatum decided by Berkeley and Broome. By studying authentic specimens of Vittadini, and Berkeley and Broome, it was possible to establish the three clades as T.
