The first of 72 equally most parsimonious trees obtained from an analysis of the ITS sequence alignment (TL = 552 steps, CI = 0.621, Rl = 0.938, RC = 0.583). The numbers at the nodes represent bootstrap support values based on 1000 resamplings and thickened lines indicate those branches present in the strict consensus tree. Type and ex-type strains are indicated in bold and the scale bar indicates 30 changes. The culture collection or GenBank accession number is indicated for each sequence, followed by the isolation source and country of origin. The tree is rooted to Seiridium phylicae (GenBank accession KC005787).
