The genome sequence and gene models of Colletotrichum orchidophilum IMI 309357 have not been determined by the JGI, but were downloaded from NCBI on Oct 25, 2016. In order to allow comparative analyses with other fungal genomes sequenced by the Joint Genome Institute, a copy of this genome is incorporated into Mycocosm. Please note that this copy of the genome is not maintained by NCBI and is therefore not automatically updated.

The genus Colletotrichum (phylum Ascomycota, subphylum Sordariomycetes, order Glomerelalles) contains at least 150 species divided into ten major clades. One of the largest of these is the Colletotrichum acutatum species complex (CAsc), which includes fungal pathogens that infect a wide diversity of plants in natural and managed ecosystems. The species complex has a very wide host range, and strains have been associated with diseases of more than 90 genera of plants and at least three insect species. The complex taxonomy of CAsc reflects a complexity in evolutionary history, likely brought about by recent host jumps and/or changes in host range followed by adaptation. The CAsc also display great diversity of reproductive behaviors although most species seem to have lost their mating capability. Thus, the CAsc are excellent candidates for studying the process of speciation, host adaptation and the evolution of mating behavior.

Colletotrichum orchidophilum is closely related to the CAsc but is not considered to be part of it. It is thought to be the closest common ancestor to the CAsc.
