Phylogenetic relationships inferred from maximum parsimony analysis of ITS-rDNA sequences of 36 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 records: Lentinus sajor-caju, having GenBank number KY649463 and herbarium number MFLU 12-1478; Lentinus squarrosulus, having GenBank number KY649464 and herbarium number MFLU 12-1228; Lentinus velutinus, having GenBank number KY649465 and herbarium number MFLU 12-1123 are shown in bold and blue. The topology is rooted with Panus lecomtei. Evolutionary analysis was conducted in PAUP 4.0b 10.
