Perenniporiopsis

The first phylogenetic analysis ( Figure 1 ) included 77 taxa, which encompassed the sequences of two new strains. The tree was constructed using the combined ITS and LSU sequences, totalling 1,950 characters with gaps: 897 characters for ITS and 1,053 characters for LSU. The best scoring maximum likelihood tree (-20718.599316) is shown in Fig. 1 . Tree topologies of the ML and MP were consistent with the Bayesian analysis. The dataset represents Perenniporiopsis and other related taxa, with Stereum hirsutum (NBRC 6520) and Heterobasidion annosum (PFC 5252) as the outgroup taxa. The dataset comprised 1950 total characters, of which 1016 were constant, 704 variable characters were parsimony-informative, and 230 characters were parsimony-uninformative.

FIGURE 1. The phylogram generated from the maximum likelihood analysis of combined ITS and LSU sequences from Perenniporiopsis and related taxa (Final likelihood value of -20718.599316). The tree is rooted with Stereum hirsutum (NBRC 6520) and Heterobasidion annosum (PFC 5252). The ex-type strains are indicated in bold, and the new species are indicated in red. Bootstrap support values ≥65% from the maximum likelihood (ML) and Bayesian posterior probabilities (PP) values ≥0.90 are given above the nodes.
