我们首次描述了真菌Diaporthe toxicoosp. nov.，其引起漆树的茎和枝上的溃疡病。我们进行了系统发育分析，使用组合的多基因序列数据从rDNA内部转录间隔区序列和部分基因的钙调蛋白，组蛋白H3，β-微管蛋白，和翻译延伸因子1-α。结果表明，D. toxicobacterium占据一个单系分支，支持度很高。虽然有10个种在亲缘关系上与D.毒力、α分生孢子大小和缺乏β和γ分生孢子的形态特征支持该真菌与那些密切相关的种的区别。目前尚未发现该物种的有性形态结构。通过对T. Vernicifluum。
We describe for the first time the fungus Diaporthe toxicodendri sp. nov., which causes canker disease on the stems and twigs of Toxicodendron vernicifluum. We conducted a phylogenetic analysis using combined multigene sequence data from the rDNA internal transcribed spacer sequence and partial genes for calmodulin, histone H3, beta-tubulin, and translation elongation factor 1-alpha. The results indicate that D. toxicodendri occupies a monophyletic clade with high support. Although 10 species are phylogenetically closely related to D. toxicodendri, morphological characteristics of size of alpha conidia and lacking of beta and gamma conidia support the distinction of this fungus from those closely related species. No sexual morphic structures have yet been found for the species. The pathogenicity of this species was confirmed by the inoculation test to T. vernicifluum.
