Abstract
Botrytis is one of the oldest, most well studied, and most economically important fungal taxa. Nonetheless, many species in this genus have remained obscured for nearly 300 years because of the difficulty in distinguishing these species by conventional mycological methods. Aided by the use of phylogenetic tools, the genus is currently undergoing a taxonomic revolution. The number of putative species in the genus has nearly doubled over the last 10 years and more species are likely to be discovered in the future. The implementation of phylogenetic species recognition concepts in Botrytis is providing for more resolution on the relatedness among species than ever before, and this has helped to overcome issues in historical species recognition using morphology, sexual crosses, and pathogenicity tests. Meanwhile, the use of genetic tools is helping to reveal surprising insight into this archetypal necrotroph’s behavior, making these approaches increasingly important in species recognition and identification. As Botrytis taxonomy continues to evolve at a rapid pace, researchers should be encouraged to continue to employ the powerful tool of phylogenetics while considering how it fits into a larger framework of classical Botrytis species recognition. Starting points for discussion on how to move forward with Botrytis species recognition are included herein, with an emphasis on the implications and utility of new species descriptions.
