摘要

摘要通过对美国德克萨斯州亚热带地区的长期野外调查，在Pezizomycotina中引入了3个新属和3个新种，以适应缺乏DNA序列数据的新分类群或先前描述的分类群。在dothideomycates中，Piepenbringia, gen. 11被建立在与Kirschsteiniotheliales中的T. exilis模式种相距甚远的多重带孢（Pleosporales incertae sedis）上。从小沙巴（壁虎科）的枯叶上采集到的美洲棘球绦虫，sp. 11 .形成了一个独特的单系谱系，与模式种棘球绦虫的代表性菌株有一定的距离。在sordariomycate中，Distoseptisporales （Distoseptisporales）中的sabalicola带绦虫（Taeniolella sabalicola），也与dothideomycate中的T. exilis相距遥远，引入了Pseudotaeniolella， gen11 .)。从挂藤的死茎上收集到的ampelinus副青霉属（Parapenzigomyces）， gen. et sp. 11 .在Xylariales中形成了一个强有力的支持谱系，与Chaetosphaeriales中的Penzigomyces的模式种P. nodipes有很大的距离。通过对前型材料的研究，提出了鞭毛假单胞菌的新组合。Sporidesmina扩展到容纳Stanjehughesia floridensis和其他一些类似Stanjehughesia的真菌，这些真菌聚集在木属中一个独特的谱系incertae seis中。它们与毛纲的模式种St. hormiscioides相距较远；因此，Sporidesmina提出了五种新的组合。acrodicys holubovae, sp. 11 (Acrodictyaceae, sordariomyetes intercertae sedis)，采集于Arundinaria sp. （Poaceae）的死秆上，在系统发育上与其他acrodicys种类有棍棒状或梨形分生孢子，具有3-4个横隔和明显的孔。由于其与几个异败菌属的相似性，对其身份进行了修正。提出了新的组合D. foveolata，并将其名称简化为其同义词。该属也扩展到包括以前被忽视的树状分生。新记录于北美洲的Pleopunctum ellipsoideum、d.p euseptata和d.m eiingensis。为脆弱孢子菌和柏克莱管菌提供了新的系统发育定位。

New genera, species, combinations, and synonyms of saprobic Dothideomycetes and Sordariomycetes from subtropical Texas, USA.

As a result of long-term field work in subtropical Texas, USA, three novel genera and three new species are introduced in Pezizomycotina to accommodate new or previously described taxa lacking DNA sequence data. In the Dothideomycetes, Piepenbringia, gen. nov. is established for Taeniolella multiplex (Pleosporales incertae sedis) distant from the type species T. exilis in Kirschsteiniotheliales. Ernakulamia americana, sp. nov. (Tetraplosphaeriaceae, Pleosporales), collected on dead leaves of Sabal minor (Arecaceae), forms a distinct monophyletic lineage distant from representative strains of E. cochinensis, the type species. In the Sordariomycetes, Pseudotaeniolella, gen. nov. is introduced for Taeniolella sabalicola in Distoseptisporaceae (Distoseptisporales), also distant from T. exilis in the Dothideomycetes. Parapenzigomyces ampelinus, gen. et sp. nov. collected on dead stems of hanging vines, forms a strongly supported lineage in Xylariales distant from the type species of Penzigomyces, P. nodipes, in Chaetosphaeriales. A new combination in Parapenzigomyces is proposed for P. flagellatus after examination of ex-type material. Sporidesmina is expanded to accommodate Stanjehughesia floridensis and a few other stanjehughesia-like fungi that cluster together in a distinct lineage incertae sedis in Xylariales. They are distant from St. hormiscioides, the type species in Chaetosphaeriales; therefore, five new combinations in Sporidesmina are proposed. Acrodictys holubovae, sp. nov. (Acrodictyaceae, Sordariomycetes incertae sedis), collected on dead culms of Arundinaria sp. (Poaceae), is phylogenetically distant from other Acrodictys species having clavate or pyriform conidia with 3-4 transverse septa and distinct pores. The identity of Solicorynespora foveolata is revised due to its similarity to several Distoseptispora species. The new combination D. foveolata is proposed, and the name D. bambusae is reduced to its synonym. The genus is also expanded to include previously overlooked tretic conidiogenesis. Pleopunctum ellipsoideum, D. euseptata, and D. meilingensis are newly recorded from North America. Novel phylogenetic placements are provided for Sporidesmium fragilissimum and Tubeufia berkeleyi.

期刊介绍： International in coverage, Mycologia presents recent advances in mycology, emphasizing all aspects of the biology of Fungi and fungus-like organisms, including Lichens, Oomycetes and Slime Molds. The Journal emphasizes subjects including applied biology, biochemistry, cell biology, development, ecology, evolution, genetics, genomics, molecular biology, morphology, new techniques, animal or plant pathology, phylogenetics, physiology, aspects of secondary metabolism, systematics, and ultrastructure. In addition to research articles, reviews and short notes, Mycologia also includes invited papers based on presentations from the Annual Conference of the Mycological Society of America, such as Karling Lectures or Presidential Addresses.
