滇西北地区木质淡水真菌多样性中国目前正在研究中。收集和鉴定了4个新的管状化石分类群。其中，云南拟螺旋霉菌(Parahelicmyces yunnanensis sp.)Nov.和黑隔管藻Tubeufia nigroSeptus sp.11月结合ITS、SSU、TEF1-α和RPB2序列的形态和分子系统发育分析，作为新种被引入。文中提供了新种的详细描述和插图，并讨论了与相似分类群的形态比较。提供了两株水生新螺旋霉菌和圆柱状丝状螺旋菌。
Diversity of lignicolous freshwater fungi in northwestern Yunnan, China is currently being studied. Four fresh collections of tubeufiaceous taxa were collected and identified. Among of them, Parahelicomyces yunnanensis sp. nov and Tubeufia nigroseptum sp. nov. are introduced as new species based on morphology and molecular phylogenetic analysis of combined ITS, SSU, TEF1-alpha and RPB2 sequence data. The detailed descriptions and illustrations of the new species are provided, as well as the morphological comparison with similar taxa are discussed. Two strains of Neohelicomyces aquaticus and Tubeufia cylindrothecia are provided.
