Phylogenetic analyses based on a combined dataset of ITS, LSU, SSU, and rpb2 sequence data robustly place Nigrellomyces within the family Pleurotheciaceae (Pleurotheciales, Savoryellomycetidae), with strong statistical support. The genus is currently known only from its asexual morph, which is characterized by macronematous, mononematous, erect, unbranched, septate conidiophores; polyblastic, integrated, terminal or intercalary, sympodial proliferations; denticulate conidiogenous cells with swollen apices; and acrogenous, subglobose to globose, ovoid to obovoid, or ellipsoidal, aseptate, guttulate conidia. Morphological comparisons reveal that Nigrellomyces displays a cordana-like conidiogenesis that is distinct from other genera in Pleurotheciaceae, which typically exhibit acrodictys-, helicoön-, monodictys-, or dactylaria-like asexual morphs. This study provides a comprehensive morphological description, illustrations, and comparative interpretation of the new taxon. An updated phylogenetic backbone tree of Pleurotheciaceae is also presented, improving resolution of intergeneric relationships within the family. The discovery of N. aquaticus not only expands the taxonomic framework of Pleurotheciaceae but also contributes to a deeper understanding of the species richness, ecological roles, and biogeographic distribution of lignicolous freshwater fungi in Southwest China, particularly in the underexplored region of Guizhou Province.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"122 ","pages":"277-292"},"PeriodicalIF":3.6,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12464557/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Walnut stem blight and dieback is one of the most severe diseases affecting walnut productivity and quality in the country. To clarify the pathogens responsible for walnut stem disease, a comprehensive nationwide survey was conducted. From 276 walnut stem blight and dieback samples collected across seven provinces in China, 292 isolates of Diaporthe spp. were obtained. Both morphological characteristics and phylogenetic analyses based on partial ITS, cal, his3, tef1-α, and tub2 loci were used for fungal identification. Seven species of Diaporthe were identified, including one novel species, D. yunnana. Diaporthe species were most abundant in subtropical southwest China, less common in the temperate north, and absent in Xinjiang. Koch's postulates confirmed that all seven Diaporthe species could cause blight and dieback on walnut branches, with pathogenicity varying significantly among the species. D. eres and D. rostrata were the most virulent, followed by D. sackstonii, D. amygdali, D. citrichinensis, and D. yunnana, while D. psoraleae-pinnatae was the least aggressive.
