Maximum likelihood phylogenetic tree generated from ITS, LSU, rpb2, and tef1–α sequence data of selected taxa from Niessliaceae. The tree is rooted with four taxa from Nothoacremoniaceae (CBS 416.68, CBS 190.70, CBS 587.73, and CBS 397.70B). The newly generated sequence is in bold blue. Holotype and ex-type strains are in bold text. Bayesian posterior probabilities (BYPP) ≥ 0.95 and maximum likelihood bootstrap (MLBS) values ≥ 70% are shown at the nodes.
