螺旋孢丝孢菌是管孢目中一个形态学上十分有趣的类群。本研究利用形态学特征和系统发育分析对10种螺旋孢子无性变型和2种有性变型进行了鉴定。本文报道了新棘柱藻（Neoacanthostigma）四新种，即新棘柱藻N. aquaticum、水刺N. brunneisporum、褐孢霉N. guangxiense和N. Latisporum）进行了描述和举例说明。结合ITS、LSU和TEF1 α序列数据的系统发育分析将所有分类群归入新棘柱藻属（管藻目，管藻科），为新分类群的建立提供了证据。并对新棘柱头菌与其它螺旋孢子菌的形态特征进行了比较和讨论。文中还提供了新棘柱藻属所有种的检索表。
Helicosporous hyphomycetes are a morphologically fascinating group of Tubeufiales. Ten dematiaceous helicosporous asexual morphs and two sexual morphs collected from aquatic habitats are characterized in this study using morphological features and phylogenetic analyses. Four new species of Neoacanthostigma, viz. N. aquaticum, N. brunneisporum, N. guangxiense and N. latisporum, are described and illustrated. The phylogenetic analyses of combined ITS, LSU and TEF1 alpha sequence data place all taxa in the genus Neoacanthostigma (Tubeufiaceae, Tubeufiales) and provide evidence to support the establishment of the new taxa. The differentiating morphological characters of Neoacanthostigma with other helicosporous species are compared and discussed. A key to all Neoacanthostigma species is also provided.
