Neoplagiostoma Z. X. Zhang & X. G. Zhang

Notes.

The genus Pyrispora was introduced with Py. castaneae as its type species, isolated from Castanea mollissima in China ( Jiang et al. 2021 a). Later, Pseudoplagiostoma castaneae was described from the same host and was subsequently treated as a synonym of Py. castaneae ( Mu et al. 2022, 2024 b). Recently, Zhang et al. (2025) proposed the genus Neoplagiostoma , typified by N. castaneae based on the basionym Ps. castaneae , but failed to compare it with Pyrispora either morphologically or phylogenetically. Our study confirms that N. castaneae and Py. castaneae are identical in host association, geographic distribution, morphology, and phylogenetic placement (Fig. 1 ). Therefore, Neoplagiostoma should be regarded as a synonym of Pyrispora .
