单系类群生物多样性的形态和分子差异是具有挑战性的。本研究的目的是探讨能否通过微形态特征来验证塞巴菌目的高分子多样性。因此，我们对塞巴目的所有属模式种和其他代表性分类群进行了分子和形态研究。我们的结果鼓励我们理清一些系统发育和分类学上的差异，并改进塞巴尼亚分类。这包括属界和隶属关系，以及更高的分类单元分组。在科的水平上，我们重新定义了Sebacinaceae，以前的Sebacinales A组，并将其与Sebacinales组B区分开来。为了分类的目的，我们建议将Paulisebacina、Craterocolla、Chaetosperum、Globulisebacina、Tremelloscypha和Sebacinae归入Sebacinaceae和Piriformospora，将Serendiate归入Sebacinales组B。在较低的分类水平上，我们建议在Sebacinaceae(1)内引入Paulisolobacina for Sebacinales allantoidae，(2)将Efiobasileylae转移到一个新的单一属--Globulisebacina，(3)将其包括在Sebacinaceae和Piriformospora中，(4)将Sebacito Treamsia转移到Sebacinales组B中，(5)结合(5)。他妈的和S。在它们自己的属Helvellosebacina中，(6)将Tremelloendronspp.进入Sebacina，(7)定义。Epigaeas.str.无孢子囊和鞭毛状双核植物，但有星形休眠孢子，(8)分离。孢子囊病，同时具有不规则萌发的孢子和不明显的囊虫，以及。鞭状植物由鞭状双核植物组成。Epigaeas.str.根据分子差异，目前还不能从形态上区分Sebacina中的其他支系。
Morphological and molecular discrepancies in the biodiversity of monophyletic groups are challenging. The intention of this study was to find out whether the high molecular diversity in Sebacinales can be verified by micromorphological characteristics. Therefore, we carried out molecular and morphological studies on all generic type species of Sebacinales and additional representative taxa. Our results encouraged us to disentangle some phylogenetic and taxonomic discrepancies and to improve sebacinalean classifications. This comprises generic circumscriptions and affiliations, as well as higher taxon groupings. At the family level, we redefined the Sebacinaceae, formerly the Sebacinales group A, and set it apart from the Sebacinales group B. For taxonomical purposes, it seems appropriate to referPaulisebacina, Craterocolla, Chaetospermum, Globulisebacina, Tremelloscypha,andSebacinato the Sebacinaceae andPiriformospora,andSerendipitato the Sebacinales group B. At the lower taxonomic level, we propose within the Sebacinaceae (1) to introducePaulisebacinaforSebacina allantoidea, (2) to transferEfibulobasidium rolleyiinto a new monotypic genus,Globulisebacina, (3) to includeTremellostereuminTremelloscypha, (4) to transferSebacina amesiiintoTremelloscypha, (5) to combineS. helvelloidesandS. concrescensin their own genus,Helvellosebacina, (6) to transferTremellodendronspp. intoSebacina, (7) to defineS. epigaeas.str. without cystidia and flagelliform dikaryophyses, but with star-shaped resting spores, and (8) to separateS. cystidiatawith simultaneously irregular germinating spores and inconspicuous cystidia, andS. flagelliformiswith flagelliform dikaryophyses fromS. epigaeas.str. Additional clades inSebacina, based on molecular differences, cannot be distinguished morphologically at present.
