Abstract
Circinotrichum , Gyrothrix and Vermiculariopsiella represent a complex of dematiaceous, setose, saprobic hyphomycetes that are commonly collected on plant litters in tropical, subtropical to temperate climates. Multi-locus analysis (ITS, LSU, rpb2 ) and morphological studies revealed that Gyrothrix and Circinotrichum are polyphyletic and species belong to 10 genera grouping in three different clades within Xylariales , named Coniocessiaceae ( Circinotrichum and Pirozynskiomyces gen. nov.), Microdochiaceae ( Selenodriella and the resurrected genus Peglionia ) and the new family Gyrothricaceae ( Gyrothrix , Xenoanthostomella , Neogyrothrix gen. nov., Pseudocircinotrichum gen. nov., and Pseudoceratocladium gen. nov.). Vermiculariopsiella ( Vermiculariopsiellales , Vermiculariopsiellaceae ) is emended for species with setose sporodochia with simple setae ( V. dichapetali , V. eucalypticola , V. immersa , V. pini , V. spiralis , V. australiensis sp. nov.) while Vermiculariopsis is resurrected and includes setose fungi with branched setae ( Vs. dunni , Vs. eucalypti , Vs. eucalyptigena , Vs. lauracearum , Vs. microsperma , Vs. pediculata and Vs. castanedae sp. nov.).
