See text Colletotrichum (sexual stage: Glomerella) is a genus of fungi that are symbionts to plants as endophytes (living within the plant) or phytopathogens.

[1] The history of the Colletotrichum genus is a case study on the tension between the lumpers and splitters.

[4] The biggest recent shift has been from a definition (of both the genus and the species within it) based on morphology to a definition based on a combination of morphology and molecular phylogenetics.

or sensu lato (in the broad sense) while that same name when referring to the specific species within the species complex will have the suffix of s.s. or sensu stricto (in the strict sense).

[6] If history is any indicator of the future, then the list of species complexes and species within this genus will continue to be redefined and reorganized as more information becomes available.
