The first of two equally most parsimonious trees (TL = 404; CI = 0.735; RI = 0.871; RC = 0.640) resulting from a parsimony analysis of the ITS alignment representing Acrocalymma and related genera. The bootstrap support values from 1 000 replicates are indicated at the nodes and the scale bar represents the number of changes. Thickened branches reflect those branches present in the strict consensus tree. Species of Acrocalymma are highlighted in the yellow and green blocks. Additional species names of interest to this study are shown in bold text. The tree was rooted to Alternaria consortialis (GenBank KC584247).
