广义Strigula sensu lato以前已经根据表型特征被定义为一个相当广泛的属，包括生长在广泛基质上的热带至温带物种。在这项研究中，基于多位点系统发育方法，我们表明叶生物种形成了六个界限明确的分支，这些分支与诊断表型特征相关，包括叶状体形态、总苞和囊壳的碳化、子囊孢子尺寸和大分生孢子的类型。鉴于拓扑结构，与5的6个分支出现在长茎分支，和强大的表型分化的分支之间，我们认识到这些在属的水平，主要利用以前建立的属名。其中，Phylloporis、Puiggariella、Raciborskiella和Racoplaca等4个属的S. phyllogena、S. nemathora，S. janeirensis和S. subtilissima组，而一个新属，Serusiauxiella gen. nov.，引入了一个新的谱系，具有独特的大分生孢子。非叶生种S. jamesii与这六个叶生谱系不密切相关，但与Flavobathelae和Phyllobathelae聚类，揭示了它作为一个额外的未描述的属级谱系在其他地方被处理。在新属Serusiauxiella中描述了3个新种：丝状Serusiauxiella filifera sp. nov.，S.鞭毛虫属，和S.此外，还提出了10个新组合：南方斑孔菌Phylloporis austropunctata comb. nov.，辐射蕨P.radiata comb.nov.，P.vulgaris comb.nov.，聚丛矮藓十一月，线霉P.nemathoracomb.nov.，nov.，斑裸板藻R. melanobapha comb. nov.，R. transversoundulata和R.我们还报告了一个特殊的，以前未被承认的生长行为的macrosoconidial附属物在Strigula s.lat.
Strigula sensu lato has been previously defined based on phenotype characters as a rather broad genus including tropical to temperate species growing on a wide array of substrata. In this study, based on a multilocus phylogenetic approach, we show that foliicolous species form six well-delimited clades that correlate with diagnostic phenotype features, including thallus morphology, carbonization of the involucrellum and excipulum, ascospore dimensions, and type of macroconidia. Given the topology, with five of the six clades emerging on long stem branches, and the strong phenotypical differentiation between the clades, we recognize these at the genus level, making mostly use of previously established genus names. Four genera, namely Phylloporis, Puiggariella, Raciborskiella, and Racoplaca, are resurrected for the S. phyllogena, S. nemathora, S. janeirensis, and S. subtilissima groups, respectively, whereas one new genus, Serusiauxiella gen. nov., is introduced for a novel lineage with peculiar macroconidia. The only sequenced non-foliicolous species, S. jamesii, is not closely related to these six foliicolous lineages but clusters with Flavobathelium and Phyllobathelium, revealing it as an additional undescribed genus-level lineage being treated elsewhere. Within the new genus Serusiauxiella, three new species are described: Serusiauxiella filifera sp. nov., S. flagellata sp. nov., and S. sinensis sp. nov. In addition, ten new combinations are proposed: Phylloporis austropunctata comb. nov., P. radiata comb. nov., P. vulgaris comb. nov., Puiggariella confluens comb. et stat. nov., P. nemathora comb. nov., P. nigrocincta comb. nov., Racoplaca maculata comb. nov., R. melanobapha comb. nov., R. transversoundulata, and R. tremens comb. nov. We also report on a peculiar, previously unrecognized growth behaviour of the macroconidial appendages in Strigula s.lat.
