Maximum Likelihood (RAxML) tree, based on analysis of a combined dataset of LSU, ITS and RPB2 sequence data. Bootstrap support values for ML and MP greater than 75% and Bayesian posterior probabilities greater than 0.95 are given near nodes, respectively. The tree is rooted with Aquapteridospora fusiformis (MFLU 18–1601) and A. lignicola (MFLUCC 15–0377). The ex-type strains are indicated in bold and the new isolates are in red.
