Abstract：
Four species of myxomycetes (Arcyria pseudodenudata, Diderma europaeum, Lycogala irregulare, and Trichia armillata) new to China were observed via light microscope and scanning electron microscope, and detailed descriptions and illustrations are provided, along with comparisons with related species. Among them, A. pseudodenudata was discovered for the first time outside of the type locality, D. europaeum was discovered for the first time outside of Europe, and L. irregulare and T. armillata were reported again after being named. Phylogenetic analyses based on nuclear 18S rDNA and elongation factor-1 alpha sequences or nuclear 18S rDNA and cytochrome oxidase subunit I sequences was performed to provide a molecular basis for morphological identification. These specimens were deposited in the Herbarium of Fungi of Nanjing Normal University.
摘要：
四种粘菌（伪藻，欧洲双皮病，Lycogalaregulare，通过光学显微镜和扫描电子显微镜观察到了中国新出现的Trichiaarmillata），并提供了详细的描述和插图，以及与相关物种的比较。其中,A.在类型局部性之外首次发现了伪数据，欧洲是第一次在欧洲以外的地方被发现,以及L.regular和T.armillata在被命名后再次被报告。进行了基于核18SrDNA和延伸因子1α序列或核18SrDNA和细胞色素氧化酶亚基I序列的系统发育分析，为形态学鉴定提供了分子基础。这些标本保存在南京师范大学真菌标本室。
