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.

葡萄孢属是最古老，研究最充分，最经济重要的真菌类群之一。然而，由于难以通过常规真菌学方法区分这些物种，该属中的许多物种仍被掩盖了将近300年。借助于系统发育工具的帮助，该属目前正在经历一场分类学革命。在过去的十年中，该属中假定的物种数量几乎翻了一番，将来可能会发现更多的物种。系统发育种识别概念在葡萄孢属中的实施正提供比以往任何时候都更多的关于物种之间关联性的解决方案，这有助于克服使用形态学，性杂交和致病性测试的历史物种识别中的问题。同时，遗传工具的使用有助于揭示对该原型坏死生物行为的令人惊讶的见解，从而使这些方法在物种识别和鉴定中变得越来越重要。随着葡萄孢菌分类学继续快速发展，应鼓励研究人员继续使用功能强大的系统遗传学工具，同时考虑它如何适合更大的经典葡萄孢菌种识别框架。讨论如何与Botrytis一起前进的起点 物种识别包括在本文中，重点放在新物种描述的含义和效用上。
