Two distinct populations of Arnica montana, an endangered medicinal plant, were studied under field conditions. The material was investigated using microscopic and molecular methods. The analyzed plants were always found to be mycorrhizal. Nineteen arbuscular mycorrhizal fungal DNA sequences were obtained from the roots. They were related to Glomus Group A, but most did not match any known species. Some showed a degree of similarity to fungi colonizing liverworts. Conventional analysis of spores isolated from soil samples allowed to identify different fungal taxa: Glomus macrocarpum, Glomus mosseae, Acaulospora lacunosa, and Scutellospora dipurpurescens. Their spores were also isolated from trap cultures.
两种不同的高山火绒草种群，一种濒危药用植物，在野外条件下进行了研究。使用显微镜和分子方法对材料进行了分析。分析的植物总是被发现是菌根的。从根部分离出了 19 个丛枝菌根真菌 DNA 序列。它们与 Glomus Group A 有关，但大多数与已知物种不匹配。有些与定殖在肝蕨上的真菌有一定的相似性。从土壤样本中分离出的孢子的常规分析可以识别不同的真菌分类群：巨孢囊霉、摩西管囊霉、腔孢囊霉和紫斑节丛孢。它们的孢子也从诱捕培养物中分离出来。
