Phylogenetic tree showing the relationship of Pleurostoma hongkongense HKU44T to its closely related species within the genus Pleurostoma. The tree was inferred from the concatenated sequence data of the internal transcribed spacer (ITS) region, partial β-tubulin gene, partial 18S nrDNA and partial 28S nrDNA by the maximum likelihood method with the substitution model T92 (Tamura 3-parameter model) + G (gamma-distributed rate variation) + I (estimated proportion of invariable sites). The scale bar indicates the estimated number of substitutions per base. Only nodes that were well supported by the maximum-likelihood method (≥70% bootstrap support) have their bootstrap support, calculated from 1,000 replicates, shown; and all these nodes were also well supported by the Bayesian inference method (posterior probabilities ≥0.99). The DDBJ/ENA/GenBank nucleotide accession numbers for Jattaea algeriensis STE-U 6201T are EU367446 (ITS), EU367466 (β-tubulin), EU367462 (18S nrDNA) and EU367456 (28S nrDNA).
