Sordariomycetes is an earlier-introduced and one of the widely distributed class of Ascomycota. The class was initially classified based on morphology in having inoperculate and unitunicate asci. With the development of DNA based phylogenetic analysis, several undetermined or polyphyletic members of Sordariomycetes were reclassified. However, not all species belonging to this class have been sequenced and analyzed. There are a number of species, especially those old and poorly studied ones which have never been sequenced before and not even recollected again for further taxonomic verification. One of the main objective in this study is to revise and update the taxonomy of several well-known early and poorly studied species whose classification are still obscure. Herein, we re-examined the type materials and/or authentic specimens together to explore 74 relatively poorly-studied genera, which mainly belong to Boliniales, Calosphaeriales, Chaetosphaeriales, Jobellisiales, and Sordariales classified under Diaporthomycetidae and Sordariomycetidae. We provide descriptions, notes, figures and/or drawings and discussed their phylogenetic relationships. As a result, the monotypic Jobellisiales is transferred from Hypocreomycetidae to Diaporthomycetidae. Based on phylogenetic analysis, the polyphyletic Lasiosphaeriaceae is divided into five families, Bombardiaceae (Apodospora, Bombardia, Bombardioidea, Fimetariella and Ramophialophora), Lasiosphaeriaceae (Anopodium, Bellojisia, Corylomyces, Lasiosphaeria, Mammaria and Zopfiella), Lasiosphaeridaceae (Lasiosphaeris), Strattoniaceae (Strattonia) and Zygospermellaceae (Episternus and Zygospermella). In addition, a new family Neoschizotheciaceae is established based on Neoschizothecium. Analysis of the type species of Boothiella, Stellatospora, Sulcatistroma and Tengiomyces placed them in Sordariaceae, Chaetomiaceae, Hypocreales and Coronophorales, respectively. We classify the genera lacking molecular data based on their morphology and expect them to be recollected; that is, Kacosphaeria in Calosphaeriales; Arnium, Biconiosporella, Camptosphaeria, Diffractella, Emblemospora, Eosphaeria, Periamphispora, Synaptospora and Tripterosporella in Sordariales; Conidiotheca in Sordariomycetes; Copromyces, Effetia, Endophragmiella and Tulipispora are accommodated in Ascomycota. Besides, we establish a new genus Neoschizothecium based on phylogenetic analysis. New combinations proposed: Camaropella amorpha, Cam. microspora, Cam. plana, Cladorrhinum grandiusculum, Cla. leucotrichum, Cla. terricola, Cla. olerum, Helminthosphaeria plumbea, Immersiella hirta, Jugulospora minor, Lasiosphaeris arenicola, Neoschizothecium aloides, Neo. carpinicola, Neo. conicum, Neo. curvisporum, Neo. fimbriatum, Neo. glutinans, Neo. inaequale, Neo. minicaudum, Neo. selenosporum, Neo. tetrasporum, Neurospora autosteira, Podospora brunnescens, P. flexuosa, P. jamaicensis, P. hamata, P. macrospora, P. spinosa, Strattonia petrogale and Triangularia microsclerotigena, T. nannopodalis, T. praecox, T. samala, T. tarvisina, T. unicaudata, T. yaeyamensis. New epithets are proposed for Apiorhynchostoma apiosporum and Podospora dacryoidea.

索达菌纲(Sordariomycetes)是子囊菌门中较早引入、分布广泛的一类。该类别最初是根据无盖子囊和单囊子囊的形态进行分类的。随着基于 DNA 的系统发育分析的发展，一些未确定的或多系的 Sordariomycetes 成员被重新分类。然而，并非所有属于这一类的物种都已被测序和分析。有许多物种，特别是那些古老且研究不足的物种，以前从未被测序过，甚至没有被再次收集以进行进一步的分类验证。这项研究的主要目标之一是修订和更新几个著名的早期和研究很少的物种的分类学，这些物种的分类仍然模糊。在此，我们重新审查了模式材料和/或真实标本，以探索74个研究相对较少的属，这些属主要属于Diaporthomycetidae和Sordariomycetidae下的Boliniales、Calosphaeriales、Chaetosphaeriales、Jobelliales和Sordariales。我们提供描述、注释、图表和/或图画，并讨论它们的系统发育关系。结果，单型 Jobellisiales 从 Hypocreomycetidae 转移到 Diaporthomycetidae。根据系统发育分析，多系的 Lasiosphaeriaceae 分为 5 个科：Bombardiaceae（Apododospora、Bombardia、Bombardioidea、Fimetariella和Ramophialophora）、Lasiosphaeriaceae（Anopodium、Bellojisia、Corylomyces、Lasiosphaeria、Mammaria和Zopfiella）、Lasiosphaeridaceae（Lasiosphaeridaceae）阋属 ), 禾本科 ( Strattonia ) ）和 Zygospermellaceae （Episternus和Zygospermella）。此外，在新裂藻属的基础上建立了一个新的新裂藻科。对Boothiella、Stellatospora、Sulcatistroma和Tengiomyces的模式种分析，将它们分别归属于Sordariaceae、Chaetomiaceae、Hypocreales和Coronophorales。我们根据形态对缺乏分子数据的属进行分类，并期望它们被重新收集；即Calosphaeriales中的Kacosphaeria ； Arnium、Bic​​oniosporella、Camptosphaeria、Diffractella、Emblemospora、Eosphaeria、Periamphispora、Synaptospora和Tripterosporella在Sordariales中；伞菌纲中的分生孢子壳；子囊菌门 (Ascomycota) 包括粪霉菌属(Coproomyces) 、埃菲蒂亚属 (Effetia )、内膜菌属 (Endophragmiella)和郁金香属 (Tulipispora) 。此外，我们基于系统发育分析建立了一个新属Neoschizothecium 。提出的新组合：Camaropella amorpha、Cam。小孢子菌，卡姆。Plana，Cl​​adorhinum grandiusculum，Cl​​a。白毛霉，Cla。加利福尼亚州泰里科拉​芥兰油、Plumbea 蠕虫、Immersiella hirta、Jugulospora 小、Lasiosphaeris arenicola、Neosphaeris aloides、Neo。卡皮尼科拉，新。圆锥花序，新。曲孢子菌，新。流苏，新。谷胶，新。不平等，尼奥。小尾，尼奥。硒孢子菌，新。四孢子菌、自脉孢子菌、布氏波多孢子菌、P .屈曲，P。牙买加, P.​浜田, P .大孢子虫，P . spinosa , Strattonia petrogale和Triangleia microsclerotigena , T .纳米波达利斯，T .普雷科克斯, T .萨马拉，T .塔尔维西纳, T .单尾目，T .耶亚门西斯。提出了Apiorhynchostoma apiosporum和Podospora dacryoidea的新绰号。
