Pyrrhoderma

The second phylogenetic analysis ( Figure 2 ) included 50 taxa incorporating the sequences of two new strains. The tree was inferred from the combined ITS and LSU sequences, which comprise 853 characters. The best scoring maximum likelihood tree (-8507.985969) is shown in Fig. 2 . The tree topologies of the ML and MP were similar to the Bayesian analysis. The dataset represents Pyrrhoderma and other related taxa, with Oxyporus populinus (Dai 8908) as the outgroup taxa. The dataset comprised 853 total characters, of which 421 were constant, 338 variable characters were parsimony-informative, and 94 characters were parsimony-uninformative.

FIGURE 2. The phylogram generated from the maximum likelihood analysis of combined ITS and LSU sequences from Pyrrhoderma and related taxa (Final likelihood value of -8507.985969).The tree is rooted with Oxyporus populinus (Dai 8908). The new newly recorded 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.
