摘　　要：Dead twigs of Aquilaria sinensis(Thymelaeaceae)with fungal fruiting bodies were collected from Xishuangbanna,Yunnan Province,China.After initial morphological observations,an interesting fungus whose morphologically resembled Peroneutypa was isolated.Molecular phylogeny of combined ITS and tub2 showed our fungal collection is phylogenetically closely related to P.mackenziei.However,in morphology,our fungal collection is distinct from P.mackenziei in having an ostiolar canal without periphyses and the absence of paraphyses.Based on unique morphological characteristics and multigene phylogenetic analyses results,our fungal isolate is described in this paper as Peroneutypa aquilariae sp.nov.In addition,this is the first report of the genus Peroneutypa from the host A.sinensis.Full description,illustrations,and a phylogenetic tree to show the placement of the new species are provided.A synoptic table of morphological characteristics in Peroneutypa reported worldwide is also provided.
