文摘

A fungus inhabiting the lesions of chestnut leaves infected with Diaporthe eres Nitschke was identified as a new species, Ophiognomonia castaneae (Ophiognomonia, Gnomoniaceae, Diaporthales). In this study, morphological characterization and multi-gene analysis of three markers [internal transcribed spacer regions nuc rDNA ITS1-5.8S-ITS2 (ITS), guanine nucleotide-binding protein subunit beta gene (MS204), and translation elongation factor 1-α gene (tef1-α)] were used to identify this previously undescribed fungus. The teleomorphic and anamorphic stages are described and illustrated.
