Thecaphora melandrii (Syd.) Vánky & M.Lutz infects species in the Caryophyllacaeae forming sori with spore balls in the floral organs. We report new finds from Britain, supported by phylogenetic analysis, that confirm its occurrence on Silene uniflora Roth. We review published and web accessible records and note the relatively few records of this smut, its sparse distribution, confined to Europe but scattered predominantly from central to eastern Europe. Analysis of the rDNA ITS and 28S sequences demonstrates little variability among specimens, even those parasitising different host genera, which suggests that the species has evolved relatively recently. Some Microbotryum species infect the same host plants, and we found two species, M. lagerheimii Denchev and M. silenes-inflatae (DC. ex Liro) G.Deml & Oberw., in the same locations as T. melandrii, identified by morphology and molecular phylogenetic analysis. These species may form a stable multi-species community of parasites of Silene uniflora.

Thecaphora melandrii的分布和寄主范围,首次记录英国

Thecaphora melandrii在Caryophyllacaeae(SYD)Vánky&M.Lutz感染的物种形成与花器官孢子球孢子囊群。在系统发育分析的支持下,我们报告了来自英国的新发现,这些发现证实了其发生在单峰粉Roth上。我们回顾了已发布的和可通过网络访问的记录,并注意到该黑穗病的记录相对较少,分布稀疏,仅限于欧洲,但主要分布在中欧和东欧。对rDNA ITS28S序列的分析表明,标本之间几乎没有变异,即使寄生于不同宿主属的标本也是如此,这表明该物种最近才进化。一些微物种感染同一寄主植物,并且我们发现两种,M. lagerheimii Denchev和M.硅烯-inflatae(DC。前里罗)G.Deml&Oberw,在相同的位置为T. melandrii,通过形态学和分子识别系统发育分析。这些物种可能会形成一个稳定的单峰甲寄生虫的多物种群落。
