In this study, we studied the genus Oropogon in one of the largest families of lichen-forming ascomycetes?Parmeliaceae and performed divergence times estimation on a multilocus species-tree using ITS substitution rate to investigate 1) the ancestral area of Oropogon, 2) the times of diversification of major clades within Oropogon, and 3) identify factors that affected the distribution and evolution of this genus. The results indicate that ancestral area of Oropogon is either widespread with subsequent separate evolution of clades in Asia and America or in the New World (America) with subsequent migration to Asia. Our results suggest that the genus originally radiated during the early Miocene, with subsequent diversification events occurring during the middle Miocene. We hypothesize that the Mi-1 glaciation had impact on the origin of the genus Oropogon, and that the rise of major mountain ranges, such as the Himalayas, resulted in an acceleration of the diversification rate in Oropogon in the Old World.} }
