Background In the last few years, many microfungi—including plant-associated species—have been reported from various habitats and substrates in Italy. In this study of pleosporalean fungi, we researched terrestrial habitats in the Provinces of Arezzo (Tuscany region), Forlì-Cesena and Ravenna (Emilia-Romagna region) in Italy. New information Our research on Italian pleosporalean fungi resulted in the discovery of a new species, Italica heraclei (Phaeosphaeriaceae). In addition, we present a new host record for Pseudoophiobolus mathieui (Phaeosphaeriaceae) and the second Italian record of Phomatodes nebulosa (Didymellaceae). Species boundaries were defined, based on morphological study and multi-locus phylogenetic reconstructions using Maximum Likelihood and Bayesian Inference analyses. Our findings expand the knowledge on host and distribution ranges of pleosporalean fungi in Italy.

添加到意大利 Pleosporinae，包括 Italica heraclei sp。十一月

背景 在过去几年中，在意大利的各种栖息地和基质中报道了许多微型真菌，包括与植物相关的物种。在这项对多孢菌的研究中，我们研究了意大利阿雷佐省（托斯卡纳地区）、弗利-切塞纳和拉文纳（艾米利亚-罗马涅地区）的陆地栖息地。新信息 我们对意大利多孢菌的研究发现了一个新物种，Italica heraclei (Phaeosphaeriaceae)。此外，我们提出了 Pseudoophiobolus mathieui (Phaeosphaeriaceae) 的新宿主记录和 Phomatodes nebulosa (Didymellaceae) 的第二个意大利记录。基于形态学研究和使用最大似然和贝叶斯推理分析的多位点系统发育重建，定义了物种边界。
