Three new species of Colletotrichum (Glomerellales, Glomerellaceae) associated with walnut (Juglansregia) anthracnose from China.

ABSTRACT: Colletotrichum species are significant pathogens of various economic plant hosts worldwide. In this study, 45 Colletotrichum isolates were obtained from symptomatic walnut leaves of walnut anthracnose in Shaanxi and Sichuan Provinces. In conjunction with morphological evidence and multi-gene phylogenetic analyses of internal transcribed spacer (ITS), actin (act), chitin synthase 1 (chs1), glyceraldehyde-3-phosphate dehydrogenase (gapdh) and beta-tubulin (tub2) sequences support the introduction of three new species, namely Colletotrichumcordae, C.guangyuanense and C.juglandium. Five species of Colletotrichum were identified to be C.fioriniae of the C.acutatum species complex, C.karsti of the C.boninense spe
