Maximum likelihood trees for ITS+LSU (left) and rpb2 (right) regions of Xylodon species. In order to assess genealogical concordance, dotted lines link the position of the same specimen in both trees. Grey boxes indicate the position of KUC8140 strain with Xylodon ovisporus and the position of X. paradoxus. Numbers over branches are maximum likelihood bootstrap (MLB) values and posterior probabilities (BPP). Voucher numbers and species names are indicated in Table 1.
