The maximum parsimony tree of 96 Helminthosporium taxa is based on ITS, LSU, rpb2, and SSU genes. The tree was rooted with Periconia pseudodigitata (KT1395). Bootstrap support values for ML greater than 75% and Bayesian posterior probabilities greater than 0.95 are given near nodes, respectively. The new isolates were in red. Ex-type strains were marked by T. The scale bar indicates 0.05 expected changes per site.
