| 1 | The families Distoseptisporaceae fam.nov.,Kirschsteiniotheliaceae,Sporormiaceae and Torulaceae,with new species from freshwater in Yunnan Province,China显示文摘During a north–south latitudinal survey of aquatic fungi on submerged wood and herbaceous material in streams in the Asian region,we collected several hyphomycetous taxa.This paper is part of a series where we provide illustrated accounts of these taxa and place them in a natural classification in the fungi.DNA sequence based phylogenies in recent literature have shown that Dendryphion,Sporidesmium and Torula-like species are polyphyletic in the phylum Ascomycota and their taxonomyhas been problematic due to a lack of understanding of the importance of morphological characters used to delimit taxa,as well as the lack of ex-type or reference strains.Based on multi-locus phylogenies together with morphology,we propose the novel family Distoseptisporaceae(Sordariomycetes)and three novel genera Neotorula(Pleosporales,Dothideomycetes),Distoseptispora(Sordariomycetes)and Pseudosporidesmium(Sordariomycetes).In addition,Dendryphion aquaticum,D.submersum,Distoseptispora fluminicola,D.aquatica,Kirschsteiniothelia submersa,Neotorula aquatica,Sporidesmium aquaticum,S.submersum and S.fluminicola are introduced as new species.Pseudosporidesmium knawiae comb.nov.is proposed to accommodate Sporidesmium knawiae in Sordariomycetes.The polyphyletic nature of Dendryphion,Sporidesmium and Torula-like species are partially resolved,but further sampling with fresh collections and molecular data of species are needed to obtain a natural classification. | HongYan Su Kevin D.Hyde Sajeewa S.N.Maharachchikumbura Hiran A.Ariyawansa ZongLong Luo Itthayakorn Promputtha Qing Tian ChuanGen Lin QiuJu Shang YongChang Zhao HongMei Chai XiaoYing Liu Ali H.Bahkali Jayarama D.Bhat Eric H.C.McKenzie DeQun Zhou | 2016 | Fungal Diversity2016，，5： | 2 |
| 2 | Dictyosporiaceae fam.nov.显示文摘Dictyosporiaceae fam.nov.is introduced to accommodate a holomorphic group of Dothideomycetes that are saprobes on decaying wood and plant debris in terrestrial and freshwater habitats.The sexual morph comprises Dictyosporium meiosporum,D.sexualis,Gregarithecium curvisporum,Pseudocoleophoma calamagrostidis and P.polygonicola.The sexual morphs are characterized by immersed to erumpent,superficial,globose to subglobose,dark brown to black ascomata,bitunicate asci,and septate,hyaline,sheathed ascospores.The asexual morphs are hyphomycetous with brown,multi-septate,cheirosporous conidia,produced from holoblastic conidiogenous cells,on micronematous conidiophores.Phylogenetic analyses of LSU,SSU and TEF1 sequence data place the genera with cheirospores in a monophyletic clade in the order Pleosporales.Phylogenetic analyses based on ITS sequence data show the family to comprise 44 distinct lineages that correspond to ten genera and an undetermined genus.Four new genera Dictyocheirospora,Dictyopalmispora,Jalapriya and Vikalpa,and eight new species Dictyocheirospora bannica,D.rotunda,D.vinaya,Dictyopalmispora palmae,Dictyosporium olivaceosporum,D.sexualis,Jalapriya pulchra,and Vikalpa lignicola,are introduced in the family. | Saranyaphat Boonmee Melvina J.D’souza Zonglong Luo Umpava Pinruan Kazuaki Tanaka Hongyan Su Darbhe J.Bhat Eric H.C.McKenzie E.B.Gareth Jones Joanne E.Taylor Alan J.L.Phillips Kazuyuki Hirayama Prapassorn D.Eungwanichayapant Kevin D.Hyde | 2016 | Fungal Diversity2016，，5： | 0 |
