Phylogram generated from neighbour-joining analysis based on LSU-rDNA sequences: Phylogenetic relationships inferred from neighbour-joining analysis of partial nuclear large subunit ribosomal RNA gene sequences of 15 taxa. The optimal tree with the sum of branch length = 0.27898332 is shown. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) are shown next to the branches. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The novel species having GenBank numbers KX364695 (LSU-rDNA) is shown in bold and blue font. Boletus edulis (European material with GenBank numbers AF050643) was considered as the out group. Evolutionary analysis was conducted in MEGA6 (Tamura 2013).
