We here taxonomically revise the suborder Massarineae (Pleosporales, Dothideomycetes, Ascomycota). Sequences of SSU and LSU nrDNA and the translation elongation factor 1-alpha gene (tef1) are newly obtained from 106 Massarineae taxa that are phylogenetically analysed along with published sequences of 131 taxa in this suborder retrieved from GenBank. We recognise 12 families and five unknown lineages in the Massarineae. Among the nine families previously known, the monophyletic status of the Dictyosporiaceae, Didymosphaeriaceae, Latoruaceae, Macrodiplodiopsidaceae, Massarinaceae, Morosphaeriaceae, and Trematosphaeriaceae was strongly supported with bootstrap support values above 96 %, while the clades of the Bambusicolaceae and the Lentitheciaceae are moderately supported. Two new families, Parabambusicolaceae and Sulcatisporaceae, are proposed. The Parabambusicolaceae is erected to accommodate Aquastroma and Parabambusicola genera nova, as well as two unnamed Monodictys species. The Parabambusicolaceae is characterised by depressed globose to hemispherical ascomata with or without surrounding stromatic tissue, and multi-septate, clavate to fusiform, hyaline ascospores. The Sulcatisporaceae is established for Magnicamarosporium and Sulcatispora genera nova and Neobambusicola. The Sulcatisporaceae is characterised by subglobose ascomata with a short ostiolar neck, trabeculate pseudoparaphyses, clavate asci, broadly fusiform ascospores, and ellipsoid to subglobose conidia with or without striate ornamentation. The genus Periconia and its relatives are segregated from the Massarinaceae and placed in a resurrected family, the Periconiaceae. We have summarised the morphological and ecological features, and clarified the accepted members of each family. Ten new genera, 22 new species, and seven new combinations are described and illustrated. The complete ITS sequences of nrDNA are also provided for all new taxa for use as barcode markers.

我们在这里从分类学上修改了麻生亚目（Pleosporales，Dothideomycetes，Ascomycota）。SSU和LSU nrDNA的序列以及翻译延伸因子1-alpha基因（tef1）是从106个马萨诸塞州分类单元中新获得的，并对该序列进行了系统发育分析，并从GenBank中检索了该子顺序中的131个分类单元的公开序列。我们认识了马萨里纳家族中的12个家庭和5个未知的血统。在先前已知的九个家庭，的单系状态Dictyosporiaceae，Didymosphaeriaceae，Latoruaceae，Macrodiplodiopsidaceae，Massarinaceae，Morosphaeriaceae和Trematosphaeriaceae强烈用96％以上的自举支撑值支撑，而的进化枝Bambusicolaceae和Lentitheciaceae适度支持。提出了两个新的科，伞形科和伞形科。所述Parabambusicolaceae被安装以容纳Aquastroma和Parabambusicola属新星，以及两个未命名Monodictys物种。该Parabambusicolaceae其特征是球状凹陷到半球状昏迷，周围有或没有周围的基质组织，多间隔，从棒状到梭形，透明子囊孢子。建立的硫科（Sulcatisporaceae）用于新属的Magnicamarosporium和Sulcatispora属和Neobambusicola。所述Sulcatisporaceae的特征在于近球形ascomata具有短ostiolar颈部，小梁pseudoparaphyses，棍棒状ASCI，宽梭形子囊孢子，和椭近球形分生孢子具有或不具条纹纹饰。属Periconia及其亲属从隔离Massarinaceae并放置在一个复活的家庭，Periconiaceae。我们总结了形态和生态特征，并阐明了每个家庭可以接受的成员。描述和说明了十个新属，22个新物种和七个新组合。还为所有新分类单元提供了nrDNA的完整ITS序列，以用作条形码标记。
