The paper by B.S. Weir, P.R. Johnston, and U. Damm provides a comprehensive review and genetic definition of the *Colletotrichum gloeosporioides* species complex. The authors define the limits of this complex genetically, based on a strongly supported clade within the *Colletotrichum* ITS gene tree. They accept 22 species and one subspecies within the complex, including *C. asiumum*, *C. cordylincola*, *C. fructicola*, *C. gloeosporioides*, *C. honi*, *C. kahawae* subsp. *kahawae*, *C. musae*, *C. nupharicola*, *C. psidii*, *C. siamense*, *C. theobromicola*, *C. tropicale*, and *C. xanthorrhoeae*. Additionally, they describe several new species and a new subspecies: *C. aenigma*, *C. aeschynomenes*, *C. alatae*, *C. alienum*, *C. aotearoa*, *C. cldiemiae*, *C. kahawae* subsp. *ciggaro*, *C. salsolae*, and *C. ti*, along with the nom. nov. *C. queenslandicum* (for *C. gloeosporioides* var. *minus*). The taxa are defined genetically using multi-gene phylogenies, and brief morphological descriptions are provided for species where available. The paper highlights the genetic and morphological challenges in distinguishing species within the complex, particularly between the Musae clade and the Kahawae clade. The authors emphasize the importance of using multiple genes, such as *rbcL* and *trnH-psb*, for reliable species-level identification, as ITS sequences alone are insufficient. The study also discusses the historical context of the taxonomic concepts surrounding *C. gloeosporioides* and its relationship with *Glomerella cingulata*.The paper by B.S. Weir, P.R.
