利用28S (LSU) rRNA基因和ITS区（ITS1、5.8S rDNA和ITS2）的部分序列，探讨了Periconiella、Ramichloridium、Rhinocladiella和Veronaea属的系统发育。根据LSU的序列数据，类似雷氏盐的物种分为8个不同的簇。这些分支包括水蛭门（Mycosphaerellaceae和Teratosphaeriaceae）、毛囊菌门（Herpotrichiellaceae）、多孢子门（Pleosporales）和五个亲缘关系不确定的子囊菌门。典型种为尖毛鼠，与musae、biverticillatum、cerophilum、verrucosum、pini和3个分别从strelizia、Musa和森林土壤中分离的新种为Capnodiales分支。人类致病性种R.和R.，连同束状革R.和R.，与Rhinocladiella（型种：Rh.）聚集在一起。atrovirens, Herpotrichiellaceae, Chaetothyriales)，并被分配到这个属。Veronaea botryosa是Veronaea属的模式种，也位于Chaetothyriales分支中，而Veronaea simplex集群作为Venturiaceae （Pleosporales）的姐妹分类群，并被置于Veronaeopsis新属中。提出了一种新的胸膜属组合——倒卵形Ramichloridium obovoideum与Carpoligna pleurothecii（变形：Pleurothecium sp., Chaetosphaeriales）。其他类似雷氏菌的分支包括R. subulatum和R. epichloës (incertae sedis, Sordariomycetes)，其中建立了一个新属Radulidium。舒氏拉氏菌（Ramichloridium schulzeri）及其变种被归入一个新属——桃金杆菌属（milmecridium）。介绍了Pseudovirgaria （incertae sedis）属，以适应发生在各种锈病真菌上的雷氏菌样分离物。从Bertia moriformis中分离出的一株Rhodoveronaea类分离物，在系统发育上与环孢菌科（Sordariomycetidae）有亲缘关系。除了Ramichloridium外，Periconiella也是多系的。为了适应与模式种P. velutina （Mycosphaerellaceae）无关的papuana (Herpotrichiellaceae)，引入了thyysanorea。
The phylogeny of the genera Periconiella, Ramichloridium, Rhinocladiella and Veronaea was explored by means of partial sequences of the 28S (LSU) rRNA gene and the ITS region (ITS1, 5.8S rDNA and ITS2). Based on the LSU sequence data, ramichloridium-like species segregate into eight distinct clusters. These include the Capnodiales (Mycosphaerellaceae and Teratosphaeriaceae), the Chaetothyriales (Herpotrichiellaceae), the Pleosporales, and five ascomycete clades with uncertain affinities. The type species of Ramichloridium, R. apiculatum, together with R. musae, R. biverticillatum, R. cerophilum, R. verrucosum, R. pini, and three new species isolated from Strelitzia, Musa and forest soil, respectively, reside in the Capnodiales clade. The human-pathogenic species R. mackenziei and R. basitonum, together with R. fasciculatum and R. anceps, cluster with Rhinocladiella (type species: Rh. atrovirens, Herpotrichiellaceae, Chaetothyriales), and are allocated to this genus. Veronaea botryosa, the type species of the genus Veronaea, also resides in the Chaetothyriales clade, whereas Veronaea simplex clusters as a sister taxon to the Venturiaceae (Pleosporales), and is placed in a new genus, Veronaeopsis. Ramichloridium obovoideum clusters with Carpoligna pleurothecii (anamorph: Pleurothecium sp., Chaetosphaeriales), and a new combination is proposed in Pleurothecium. Other ramichloridium-like clades include R. subulatum and R. epichloës (incertae sedis, Sordariomycetes), for which a new genus, Radulidium is erected. Ramichloridium schulzeri and its varieties are placed in a new genus, Myrmecridium (incertae sedis, Sordariomycetes). The genus Pseudovirgaria (incertae sedis) is introduced to accommodate ramichloridium-like isolates occurring on various species of rust fungi. A veronaea-like isolate from Bertia moriformis with phylogenetic affinity to the Annulatascaceae (Sordariomycetidae) is placed in a new genus, Rhodoveronaea. Besides Ramichloridium, Periconiella is also polyphyletic. Thysanorea is introduced to accommodate Periconiella papuana (Herpotrichiellaceae), which is unrelated to the type species, P. velutina (Mycosphaerellaceae).
