螺旋孢子丝菌是管状菌目的一个形态上相近的类群。根据形态和系统发育的证据，我们介绍了一个新的螺旋孢子属--新螺旋孢子菌属(Neohelicosporium)，包括五个新种：水生新螺旋孢子菌(Neohelicosporum Aquaticum)、广东新孢子菌(N.guangxiense)、透明新孢子菌(N.hyalosporum)、微小螺旋孢子菌(N.parvisporum)和泰兰新孢子菌(N.thailandicum)。RPB2蛋白基因数据为分析它们的系统发育提供了依据。对13个新分离株的ITS、LSU、RPB2和TEF1α序列进行了系统发育分析，为新分类群的建立提供了证据。对新螺旋孢子菌区别于其他螺旋孢子菌的形态特征进行了比较和讨论。
Helicosporous hyphomycetes are a morphologically allied group of Tubeufiales. We introduce a new helicosporous genus, Neohelicosporium, with five new species, Neohelicosporium aquaticum, N. guangxiense, N. hyalosporum, N. parvisporum, and N. thailandicum, based on morphological and phylogenetic evidence. The RPB2 protein gene data are provided to analyze their phylogeny in Tubeufiales. Phylogenetic analyses of combined ITS, LSU, RPB2, and TEF1 alpha sequence data from 13 new isolates of Neohelicosporium provided evidence to support the establishment of the new taxa. The morphological characters of Neohelicosporium that differentiate it from other helicosporous species are compared and discussed.
