Three new arbuscular mycorrhizal fungal species-, and -are described and illustrated. In the field, the three species were associated with roots of (Poaceae), (Poaceae), (Asteraceae), and (Apiaceae) colonizing maritime dunes located along the Mediterranean coast in eastern Spain. The novelty of these species is supported by morphological, molecular, and phylogenetic analyses. Single-species cultures of and were obtained using as a host plant, both forming arbuscular mycorrhizae, whereas single-species cultures from could not be obtained. Spores of usually occur in sporocarps, rarely singly in soil or inside roots. In contrast, only forms single spores in soil and occurs in sporocarps and singly in soil or inside roots. The respective small subunit, internal transcribed spacer, and large subunit (SSU-ITS1-5.8S-ITS2-LSU) nrDNA sequences placed the new species in the genera , and , all of them separated from previously described species.
描述并图示了三种新的丛枝菌根真菌物种——、和。在野外，这三种物种与位于西班牙东部沿地中海海岸的滨海沙丘上的 （禾本科）、 （禾本科）、 （菊科）和 （伞形科）的根共生。这些物种的新颖性得到了形态学、分子和系统发育分析的支持。使用 作为宿主植物获得了 和 的单种培养物，两者都形成丛枝菌根，而 则无法获得单种培养物。的孢子通常存在于子实体中，很少在土壤中或根内单独存在。相比之下，仅在土壤中形成单个孢子，而 在子实体中和土壤中或根内单独存在。新物种的小亚基、内部转录间隔区和大亚基（SSU-ITS1-5.8S-ITS2-LSU）nrDNA 序列将它们分别置于 和 属中，与先前描述的物种均分离。
