The red algal order Bangiales has been revised as a result of detailed regional studies and the development of expert local knowledge of Bangiales floras, followed by collaborative global analyses based on wide taxon sampling and molecular analyses. Combined analyses of the nuclear SSU rRNA gene and the plastid RUBISCO LSU (rbcL) gene for 157 Bangiales taxa have been conducted. Fifteen genera of Bangiales, seven filamentous and eight foliose, are recognized. This classification includes five newly described and two resurrected genera. This revision constitutes a major change in understanding relationships and evolution in this order. The genus Porphyra is now restricted to five described species and a number of undescribed species. Other foliose taxa previously placed in Porphyra are now recognized to belong to the genera Boreophyllum gen. nov., Clymene gen. nov., Fuscifolium gen. nov., Lysithea gen. nov., Miuraea gen. nov., Pyropia, and Wildemania. Four of the seven filamentous genera recognized in our analyses already have generic names (Bangia, Dione, Minerva, and Pseudobangia), and are all currently monotypic. The unnamed filamentous genera are clearly composed of multiple species, and few of these species have names. Further research is required: the genus to which the marine taxon Bangia fuscopurpurea belongs is not known, and there are also a large number of species previously described as Porphyra for which nuclear SSU ribosomal RNA (nrSSU) or rbcL sequence data should be obtained so that they can be assigned to the appropriate genus.
由于对红藻目杉藻科进行了详细的区域研究，以及基于当地专家对杉藻科植物区系的了解，随后进行了基于广泛分类群采样和分子分析的全球合作分析，红藻目杉藻科已得到修订。对157个杉藻科分类群的核小亚基核糖体RNA基因和质体核酮糖-1,5-二磷酸羧化酶大亚基（rbcL）基因进行了联合分析。确认了杉藻科的15个属，其中7个为丝状属，8个为叶状属。该分类包括5个新描述的属和2个恢复的属。这一修订构成了对该目亲缘关系和进化理解的重大变化。紫菜属现仅限于5个已描述的物种和一些未描述的物种。其他以前归入紫菜属的叶状分类群现在被认为属于新属Boreophyllum、新属Clymene、新属Fuscifolium、新属Lysithea、新属Miuraea、Pyropia属和Wildemania属。我们分析中确认的7个丝状属中有4个已经有了属名（Bangia属、Dione属、Minerva属和Pseudobangia属），目前均为单型属。未命名的丝状属显然由多个物种组成，其中很少有物种有名称。还需要进一步研究：海洋分类群红棕紫菜所属的属尚不清楚，还有大量以前被描述为紫菜的物种，应该获取它们的核小亚基核糖体RNA（nrSSU）或rbcL序列数据，以便将它们归入适当的属。
