Diaporthe camptothecicola sp. nov. on Camptotheca acuminata in China
A novel species Diaporthe camptothecicola is described and illustrated from cankers on branches of Camptotheca acuminata (Cornaceae) collected at Nanjing Agricultural University, Jiangsu Province, China. Recognition of this new species is supported by both morphology and phylogeny. The alpha conidia are hyaline, aseptate, oblong (6.2 × 1.6 μm), and inconspicuously biguttulate, similar to most species of Diaporthe. The beta conidia are hyaline, aseptate, filiform to hamate, 25.1 × 1.0 μm. Multi-locus phylogenetic analysis based on ITS, CAL, HIS, TEF1-α, and TUB2 gene regions suggests the new species belongs to Diaporthe.
