    • Figure 1. 

      Phylogram generated from maximum likelihood analysis based on combined dataset of LSU, SSU, ITS, and TEF1 sequence data. Bootstrap support values for maximum likelihood (ML) equal to or greater than 60% and Bayesian posterior probabilities (BYPP) equal to or greater than 0.97 are given above the nodes. Newly generated sequences are in dark red bold and ex-type isolates are in bold. Lophium mytilinum (AFTOL-ID 1609) and Mytilinidion rhenanum (CBS 135.45) are used as outgroup taxa.
