Maximum likelihood phylogenetic tree derived from alignments of ITS2 sequences. The best-fit nucleotide substitution model for the sequence dataset, based on the corrected Akaike (AICc) and Bayesian Information Criteria (BIC) was determined using MEGA v. 6 [39]. Hierarchical likelihood ratio tests ascertained that the Jukes-Cantor substitution model with gamma-distributed rate differences among sites was the optimal evolutionary model for phylogenetic inference. Fungal sequences collected from samples and reference sequences are labeled as in Fig. 2. Bootstrap support values are indicated as in Fig. 2.
