The genus Calonectria with its Cylindrocladium asexual morphs has been subject to several taxonomic revisions in the past. These have resulted in the recognition of 116 species, of which all but two species (C. hederae and C. pyrochroa) are supported by ex-type cultures and supplemented with DNA barcodes. The present study is based on a large collection of unidentified Calonectria isolates that have been collected over a period of 20 years from various substrates worldwide, which has remained unstudied in the basement of the CBS-KNAW Fungal Biodiversity Centre. Employing a polyphasic approach, the identities of these isolates were resolved and shown to represent many new phylogenetic species. Of these, 24 are newly described, while C. uniseptata is reinstated at species level. We now recognise 141 species that include some of the most important plant pathogens globally.

被遗忘的Calonectria系列:将旧酒倒入新袋中

过去Callinectria属及其Cylindrocladium是无性形态。这些已导致识别了116种,其中除两个物种(C. hederaeC. pyrochroa)外,所有其他物种均由ex型培养物支持并补充有DNA条码。本研究基于大量未鉴定的Calonectria在20多年的时间里,从世界各地的各种底物中收集了一些分离株,但尚未在CBS-KNAW真菌生物多样性中心的地下室中进行研究。采用多相方法,这些分离物的身份得到了解析,并显示出代表许多新的系统发育物种。其中,有24种是新描述的,而uniseptata则在物种水平上得到了恢复。现在,我们认识到141个物种,其中包括全球一些最重要的植物病原体。
