Colletotrichum neorubicola sp. nov., a new leaf anthracnose pathogen of raspberry from northeast China

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.
