The first of 1000 equally most parsimonious trees obtained from a heuristic search with 100 random taxon additions of the LSU sequence alignment. The scale bar shows 10 changes, and bootstrap support values from 1000 replicates are shown at the nodes. The novel sequence generated for this study is shown in bold. Branches present in the strict consensus tree are thickened and important lineages are colour-coded. The tree was rooted to a sequence of Phaeobotryosphaeria visci (GenBank accession DQ377868).
