Anther smuts on Silene acaulis and S. uniflora from the Outer Hebrides, Scotland, UK), are analysed using morphological and molecular techniques, and found to represent Microbotryum silenes-acaulis and M. silenes-inflatae, respectively. This is the first identification of caryophyllaceous anther smuts in the Outer Hebrides according to modern species concepts and the first report of Microbotryum silenes-acaulis confirmed by molecular analysis from the British Isles. Additionally, the genetic structure of Microbotryum silenes-acaulis, based on all currently available ITS sequences, is analysed and discussed. Seven ITS genotypes are determined for Microbotryum silenes-acaulis, including three genotypes in North America and four genotypes in Europe. Compared to European accessions, all North American accessions share specific nucleotides and are genetically divergent.

外赫布里底群岛中的硅质金合欢和单花链球菌的花药黑穗病，包括对微植物硅质-金合欢的ITS基因型的评估。

使用形态学和分子技术分析了来自英国外赫布里底的硅质高加索和独生链球菌的花药黑穗病，并发现它们分别代表了Microbotryum silenes-caulis和M. silenes-inflatae。这是根据现代物种概念在外赫布里底群岛首次发现的食肉性花药黑穗病，并且是不列颠群岛的分子分析所证实的硅微金刚藻的首份报告。此外，基于所有当前可用的ITS序列，对Microbotryum silenes-acaulis的遗传结构进行了分析和讨论。确定了7种ITS基因型，分别是北美细微硅藻-空壳菜，包括北美洲的三种基因型和欧洲的四种基因型。与欧洲的加入相比，
