Abstract An undescribed Colletotrichum species was isolated from leaf spots on Rubus idaeus (raspberry) in the summer of 2013 in the Jilin Province in northeast China. Based on morphology and ITS sequence data, it was identified as belonging to the Colletotrichum destructivum species complex. Phylogenetic analyses of combined ITS, GAPDH, ACT, CHS-1 and TUB2 sequence data revealed that the fungus represents a new species described here as Colletotrichum neorubicola sp. nov. Pathogenicity testing confirmed that this new species is pathogenic to R. idaeus. Keywords Colletotrichum neorubicola . Rubus idaeus . Pathogenicity
Introduction Colletotrichum is an important phytopathogenic genus. Colletotrichum spp. cause disease symptoms that are generally known as anthracnose on a wide range of host plants, serious economic losses and disease on leaves, stems, flowers and fruits of many plants (Cannon et al. 2012). Species of Colletotrichum were first classified based on their morphological characteristics and host ranges, but more recently on multi-locus sequence data (Weir et al. 2012). A set of protocols and approaches has been provided as guidelines for Colletotrichum research, species delimitation, classification and description of new species (Cai et al. 2009; Cannon et al. 2012; Damm et al. 2009, 2012b, 2014). Several new species

Rubus idaeus L. (raspberry) is a red-fruited species of Rubus (Rosaceae), and is native to Europe and northern Asia, central Asia and Russia. Red raspberry contains various polyphenols including anthocyanins and ellagitannins (Zhang et al. 2018). Raspberry foliage is also a nourishing source of vitamins and minerals beneficial during pregnancy (Parsons et al. 1999). Raspberry anthracnose wa
