Maximum-likelihood phylogenetic tree of Kirschsteiniothelia based on the combined ITS, LSU, and SSU sequence data. The ML and BI bootstrap support values equal to or above 80% and 0.90 are given above the nodes. Bar = 0.06 substitutions per nucleotide position. The tree was rooted to Pseudorobillarda eucalypti (MFLUCC 12-0422) and Ps. Phragmitis (CBS 398.61). Strains of the species from the present study were marked in red. Orders were indicated on the right side of the tree in blocks. Some branches are shortened according to the indicated multipliers to fit the page size, and these are indicated by the symbol (//).
