During a survey on corticolous Dothideomycetes, several collections with ascospores matching the genera Asteromassaria and Stigmatomassaria (Pleomassariaceae, Pleosporales) were revealed from dead corticated twigs of Acer, Carpinus and Tamarix. Closer morphological examination showed that their ascomata were apothecial, with a hamathecium consisting of septate, branched paraphyses, which are apically swollen at maturity. Several collections were cultured and sequenced, and a Blast search of their nuc 28S rDNA sequences revealed dothideomycetous affiliation, but without a close match to a specific family or order. Phylogenetic analyses of a multigene matrix containing a representative selection of Dothideomycetes from four genes (nuc 18S rDNA, nuc 28S rDNA, rpb2 and tef1) revealed placement within Dothideomycetes but without a supported familial or ordinal affiliation. Based on the phylogenetic analyses and morphological investigations, the new genera Asterodiscus and Stigmatodiscus, with the two new species A. tamaricis and S. enigmaticus, are described and illustrated, and placed in the new family Stigmatodiscaceae and new order Stigmatodiscales.

Asterodiscus和Stigmatodiscus，两个新的假肢十二指肠球菌属和新的柱状双鳞纲。

在上生地的调查座囊菌纲，以匹配属子囊孢子多个集合Asteromassaria和Stigmatomassaria（Pleomassariaceae，Pleosporales）从死corticated树枝透露宏碁，鹅和柽柳。仔细的形态学检查显示，它们的子囊是无神的，具有由分隔的，分支的副植物组成的形菌，在成熟时顶端会肿胀。培养了几个集合并进行了测序，对其nuc 28S rDNA序列进行的Blast搜索显示了十二指肠球菌的隶属关系，但与特定的家族或顺序没有紧密的匹配。对包含四个基因（nuc 18S rDNA，nuc 28S rDNA，rpb 2和tef 1）中代表性的丝状菌的选择的多基因基质进行系统进化分析，结果显示在丝状菌中，但是没有家族或序贯的亲缘关系。根据系统发育分析和形态学研究，新属描述和说明了带有两个新物种tamaricis和S. enigmaticus的Asterodiscus和Stigmatodiscus，并将它们置于新的Stigmatodiscaceae科和新的Stigmatodiscales中。
