Endoraecium is a genus of rust fungi that infects several species of Acacia in Australia, South-East Asia and Hawaii. This study investigated the systematics of Endoraecium from 55 specimens in Australia based on a combined morphological and molecular approach. Phylogenetic analyses were conducted on partitioned datasets of loci from ribosomal and mitochondrial DNA. The recovered molecular phylogeny supported a recently published taxonomy based on morphology and host range that divided Endoraecium digitatum into five species. Spore morphology is synapomorphic and there is evidence Endoraecium co-evolved with its Acacia hosts. The broad host ranges of E. digitatum, E. parvum, E. phyllodiorum and E. violae-faustiae are revised in light of this study, and nine new species of Endoraecium are described from Australia based on host taxonomy, morphology and phylogenetic concordance.
Endoraecium是一种锈菌属，可感染澳大利亚、东南亚和夏威夷的几种金合欢属植物。本研究基于形态学和分子学相结合的方法，对来自澳大利亚的55个标本进行了Endoraecium系统学研究。对核糖体和线粒体DNA位点的分区数据集进行了系统发育分析。恢复的分子系统发育支持了最近基于形态学和寄主范围发表的分类法，该分类法将指状Endoraecium分为五个物种。孢子形态是共同衍征，有证据表明Endoraecium与其金合欢属寄主共同进化。根据本研究，对指状Endoraecium、小叶Endoraecium、叶状Endoraecium和紫堇Endoraecium的广泛寄主范围进行了修订，并根据寄主分类学、形态学和系统发育一致性，从澳大利亚描述了9种新的Endoraecium物种。
