The genus has witnessed tremendous variations over the years in the number of species recognized, ranging from 11 to several hundreds. Host-specific fungal species, once the rule, are now the exception, with polyphagous behavior regarded as normal in this genus. The species was created to accommodate the pathogens that have the unique ability to infect green developing coffee berries causing the devastating Coffee Berry Disease in Africa, but its close phylogenetic relationship to a polyphagous group of fungi in the species complex led some researchers to regard these pathogens as members of a wider species. In this work we combine pathological, morphological, cytogenomic, biochemical, and molecular data of a comprehensive set of phylogenetically-related isolates to show that the Coffee Berry Disease pathogen forms a separate species, , and also to assign the closely related fungi, previously in subsp. , to a new species, . This taxonomic clarification provides an opportunity to link phylogeny and functional biology, and additionally enables a much-needed tool for plant pathology and agronomy, associating exclusively to the Coffee Berry Disease pathogen.
多年来，该属在被认可的物种数量上经历了巨大变化，从11种到数百种不等。曾经作为规则的寄主特异性真菌物种，如今已成为例外，多食性行为在该属中被视为正常。该物种的设立是为了容纳那些具有独特能力感染绿色发育中的咖啡浆果并在非洲引发毁灭性咖啡浆果病的病原体，但其与某物种复合体中多食性真菌群的密切系统发育关系，导致一些研究人员将这些病原体视为更广泛物种的成员。在这项工作中，我们结合了一组全面的系统发育相关分离株的病理学、形态学、细胞基因组学、生物化学和分子数据，以表明咖啡浆果病病原体形成了一个单独的物种，并且还将之前属于亚种的密切相关真菌归为一个新物种。这种分类学上的澄清为将系统发育与功能生物学联系起来提供了机会，此外还为植物病理学和农学提供了一个急需的工具，将 专门与咖啡浆果病病原体联系起来。
