从泰国不同地区的淡水木质基质中获得了7个新的有性变型和无性变型。从这些样品的单孢子分离物中获得的ITS、LSU和TEF1α序列数据与土豆科其他种进行了分析。结合ITS、LSU和TEF1α数据进行的系统发育分析表明，这些样本代表了3个新种：水生衣原体、泰兰网孢霉和黄色螺旋孢子菌。介绍了一新属--网孢菌属Dictyospora thailandica。文中提供了新分类群的形态描述和图解，并与相似分类群进行了比较。泰兰Dictyospora thailandica和Helicosporium Huang um的单个子囊孢子在MEA中产生无性分生孢子。
Seven new collections of sexual and asexual morphs of Tubeufiaceae from woody substrates in freshwater, were obtained from different regions of Thailand. ITS, LSU and TEF1 alpha sequence data obtained from single spore isolates of these collections were analyzed with other species of Tubeufiaceae. The phylogenetic analyses with combined ITS, LSU and TEF1 alpha data indicated that the collections represented three new species, Chlamydotubeufia aquatica, Dictyospora thailandica and Helicosporium flavum. A new genus, Dictyospora is introduced to accommodate Dictyospora thailandica. Morphological descriptions and illustrations are provided for the new taxa and compared with similar taxa. A single ascospore isolates of Dictyospora thailandica and Helicosporium flavum produced asexual conidia in MEA.
