Phylogenetic relationships inferred from maximum parsimony analysis of ITS-rDNA sequences of 28 taxa. 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 new Sri Lankan record: Boletellus emodensis having GenBank accession number KY649458 and herbarium number MFLU 12-1214 is shown in bold and blue. The topology is rooted with Boletus sp. Evolutionary analysis was conducted in PAUP 4.0b 10.
