03931C2BFFBBFFD1FF52FEF7FF4BFD8E.taxon	discussion	Notes: Colletotrichum xishanense formed a branch with high support values on the 6 - loci phylogenetic tree (MP = 100 %, BI = 1.00), while clustered with C. cycadis in a branch with lower support values. Morphologically, there is a difference in the size of conidia and appressoria between them. The conidial length of C. cycadis is 9.5 – 13.5 × 3 – 4 μm and the length of appressoria is 4.5 – 8 × 2 – 5.5 μm. The conidial length of C. xishanense is 13 – 17 × 4.5 – 6 μm and length of appressoria is 11.0 – 18.0 × 4.0 – 7.5 μm. On the 2 - loci phylogenetic tree, C. xishanense formed an independent branch with high support values (MP = 100 %, BI = 1.00). A BLASTn search of the sequence of strain CNUCC 453 - 2 - 3 - 1 in NCBI GenBank revealed low sequence similarity with act, apmat, chs- 1, gapdh, gs, tub 2 of other species. The most similar to its act, apmat, chs- 1, gapdh, gs, tub 2 sequences were C. camellia (97.59 %), C. arecicola (95.07 %), C. kahawae (98.54 %), C. kahawae (97.96 %), C. camelliae (97.38 %) and C. camelliae (98.33 %). Therefore, based on morphology combined with multigene phylogenetic analysis, this branch was designated as a new species in this study.	en	Zhao, Shi-Yi, Wang, Qiu-Tong, Guo, Mei-Jun, Hou, Cheng-Lin (2024): Colletotrichum xishanense as a new etiological anthracnose agent on Fagopyrum gracilipes in Yunnan Province, China.
