Pseudoplagiostoma wuyishanense T. C. Mu & J. Zhi Qiu, J. Fungi 10 (6, no. 383): 11 (2024) Synonym. Pseudoplagiostoma ilicis T. C. Mu & J. Z. Qiu Description. See Mu et al. (2024 a, 2024 b). Distribution. China. Ecology. Associated with leaf diseases of Ilex chinensis. Notes. Pseudoplagiostoma wuyishanense was described as a novel species inhabiting branches of an unidentified tree in Fujian Province, China, based on morphological and phylogenetic analyses (Mu et al. 2024 a). Subsequently, Ps. ilicis was proposed as a distinct species based on two isolates obtained from diseased leaves of Ilex chinensis in the same geographical region (Mu et al. 2024 b). However, during the establishment of P. ilicis, no comparative analysis was conducted with the previously described P. wuyishanense. Through detailed examination, it has been determined that these two taxa exhibit identical morphological characteristics and phylogenetic positions (Fig. 1; Mu et al. 2024 a, b). Consequently, in accordance with the principle of priority in taxonomic nomenclature based on publication dates, Ps. ilicis is hereby designated as a synonym of Ps. wuyishanense.
