摘要: 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.
