Three new dematiaceous hyphomycetes are described, based on collections of decaying grass and sedge samples in Hong Kong. Paratetraploa exappendiculata gen. and sp. nov. has semi-macronematous conidiophores and Tetraploa-Wke conidia, which lack an apical appendage, but have conspicuous punctate wall ornamentation. Petrakia paracochinensis sp. nov. resembles Piricauda cochinensis in having conidia which are similar in size and shape. Spadicoides versiseptatis sp. nov. is a distinctive species in having both pseudosepta and eusepta in each conidium.
