The maximum parsimony tree of 68 Nigrospora taxa is based on ITS, tef1-α, and tub2 genes. The tree was rooted with Apiospora malaysiana (CBS 102053) and A. pseudoparenchymatica (LC7234). 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 0.08 expected changes per site.
