Grapevine trunk diseases (GTDs) are destructive fungal diseases and economically important threat to grapevine industry worldwide. During a survey of vineyards in the Kurdistan Province, 233 fungal isolates were obtained that associated with various external and internal trunk diseases symptoms. Based on sequence data and morphological characteristics, 24 species belonging to 19 genera were characterized. Botryosphaeriaceae species were the most prevalent identified fungi followed by Alternaria, Sporocadaceae, Phaeoacremonium, and Didymellaceae taxa. At the species level, Botryosphaeria dothidea, Alternaria malorum, Phaeoacremonium aleophilum, Acremonium sclerotigenum, Alternaria chlamydosporigena, and Neoscytalidium dimidiatum were the most frequent identified species. Acremonium sclerotigenum, A. chlamydosporigena, A. malorum, Juxtiphoma eupyrena, and Paecilomyces formosus are new records associated with GTDs around the world. Among the four pestalotia-like species identified based on morphology and phylogenetic analyses of LSU, ITS, TEF1, and TUB2 sequence data, three species are newly described and introduced here as Seimatosporium marivanicum, Sporocadus kurdistanicus, and Xenoseimatosporium kurdistanicum. Furthermore, three new combinations are proposed, including Sporocadus corni, Spo. italicus, and Spo. pseudocorni. Pathogenicity of 15 species was studied on cultivars Rasha and Bidaneh Sefid in field conditions. The pathogenicity of Neoscytalidium novahollandiae, B. dothidea, Ph. aleophilum, and Phaeomoniella chlamydospora was confirmed in field conditions.

Seimatosporium marivanicum、Sporocadus kurdistanicus 和 Xenoseimatosporium kurdistanicum：伊朗库尔德斯坦省与葡萄树干病害相关的三种新的pestalotioid 物种
葡萄树干病害（GTDs）是一种破坏性的真菌病害，对全球葡萄产业构成重要的经济威胁。在对库尔德斯坦省的葡萄园进行调查期间，获得了 233 株与各种外部和内部树干疾病症状相关的真菌分离株。根据序列数据和形态特征，共鉴定出19属24种。Botryosphaeriaceae是最普遍的鉴定真菌，其次是链格孢属、孢子属、Phaeoacremonium和Didymellaceae类群。在物种水平上，Botryosphaeria dothidea 、Alternaria malorum、Phaeoacremonium aleophilum, Acremonium sclerotogenum , Alternaria chlamydosporigena和Neoscytalidium dimidiatum是最常见的鉴定物种。Acremonium sclerotogenum 、A. chlamydosporigena、A. malorum、Juxtiphoma eupyrena和Paecilomyces formosus是世界各地与 GTD 相关的新记录。在基于 LSU、ITS、 TEF1和TUB2序列数据的形态学和系统发育分析确定的四种类似pestalotia 的物种中，这里新描述并引入了三种物种，分别为Seimatosporium marivanicum、Sporocadus kurdistanicus, 和Xenoseimatosporium kurdistanicum . 此外，还提出了三种新的组合，包括Sporocadus corni、Spo。斜体和Spo。伪角 在田间条件下对栽培品种 Rasha 和 Bidaneh Sefid 研究了 15 个物种的致病性。在田间条件下证实了Neoscytalidium novahollandiae、B. dothidea 、Ph. aleophilum和Phaeomoniella chlamydospora的致病性。
