During our studies of microfungi from Thailand, Triadelphia hexaformispora sp. nov. collected from decaying wood in a freshwater habitat in Nan Province, Thailand, is described and illustrated. Based on newly generated sequences of the nuclear ribosomal DNA and partial sequence of the second largest subunit of RNA polymerase, Triadelphia species clustered in two monophyletic sister clades in Triadelphiaceae (Microascales, Hypocreomycetidae, Sordariomycetes), one clade accommodates T. heterospora, the type species of Triadelphia, T. diversa, T. loudetiae, T. hexaformisspora, and T. romanica and the second clade incudes T. moubasheri, T. pulvinata, and T. disseminata. Two other species, Triadelphia stilboidea and T. synnematofera (morphological data only) group in a separate clade for which we propose the new genus Synnematotriadelphia. Molecular clock analyses suggest that Triadelphiaceae evolved in the middle Cretaceous, ca. 105 (74–142) million years ago.

结缕草属 十一月 （S. stilboidea comb。nov。和S. synnematofera comb。nov。）和Triadelphia hexaformispora sp。十一月 在家庭Triadelphiaceae

在我们对泰国微真菌的研究中，Triadelphia hexaformispora sp。十一月 描述和说明了从泰国楠省淡水生境中腐烂的木材中收集到的水。基于RNA聚合酶的第二大亚基的核核糖体DNA和部分序列的新生成的序列，特瑞阿德尔福亚在Triadelphiaceae（两个单系姐姐进化支聚簇物种Microascales，Hypocreomycetidae，粪壳菌纲），一个进化枝容纳T. heterospora，模式种的特瑞阿德尔福亚，T.迪沃萨，T. loudetiae，T. hexaformisspora和T. romanica和第二进化枝包括 T. moubasheri，T. pulvinata和T. disseminata。另外两个物种，Triadelphia stilboidea和T. synnematofera（仅形态数据）分组在一个单独的进化枝中，为此我们提出了新的Synnematotriadelphia属。分子钟分析表明，藜科在白垩纪中期演化。105（74–142）百万年前。
