Coalescence-based species delimitation using genome-wide data reveals hidden diversity in a cosmopolitan group of lichens

Although there is an abundance of species delimitation methods on the market, most approaches depend on predefined assignment of specimens to species or populations. Assignment-free methods, which can simultaneously infer boundaries and relationships among species, are of high importance in cases, when correct pre-assignment is difficult or not at all possible. In this study, we use assignment-free multispecies coalescent-based species...
