In addition, the NCBI BLASTn search of the individual ITS sequences of our new taxon is closely related to + +H. wuzhishanense + +(X469, OL467293.1), with 89.05% similarity.

The +β-tubulin +sequence closest matches were + +H. pilgerianum + +(STMA 13455, KY624315.1), with 91.15% similarity. Our isolates compared well with a recently established new species + +H. hongheensis +E.F. Yang & Tibpromma + +, in which the differences are shown in +TABLE 2 +. The morphological differences between the other two related species and + +H. zhaotongensis + +are also listed in +TABLE 2 +. In addition, the phylogenetic analysis of combined LSU, ITS, +RPB2 +and +β-tubulin +sequences shown that the two strains of + +H. hongheensis + +(HKAS 122663, KUMCC 21-0452) separated well from + +H. perforatum + +(CBS 115281). However, our two strains of + +H. zhaotongensis + +(GMBCC1168, GMBCC1157) formed a robust clade basal to + +H. pilgerianum + +and + +H. wuzhishanense + +. Therefore, depending on morphological differences and phylogenic analyses, we introduce these two isolates as a distinct new species of + +Hypoxylon +. + + + + + \ No newline at end of file
