Abstract Two new ectocarpic arbuscular mycorrhizal fungal species, Glomus aurantium and G. xanthium (Glomeromycota), were discovered in the Mediterranean Sea dunes located in Israel, Greece, Italy, and Majorca, Spain. Mature spores of G. aurantium are deep orange, globose to subglobose, (70-)98(-120) µm diam, or ovoid, 80-120 x 110-150 µm. Their wall consists of a permanent, flexible to semiflexible, hyaline outermost layer, easily separating from a laminate, deep orange middle layer, and a flexible, hyaline innermost layer. Spores of G. xanthium usually are tightly adherent to roots and frequently occur within roots. They are light yellow to ochre, globose to subglobose, (23-)50(-70) µm diam or ovoid, 20-55 x 45-100 µm, and have a spore wall with a rigid, semi-permanent, hyaline to light yellow outermost layer adherent to a rigid, permanent, hyaline middle layer, and a laminate, light yellow to yellow ochre innermost layer. Both G. aurantium and G. xanthium formed vesicular-arbuscular mycorrhizae in one-species cultures with Zea mays. Analysis of ITS and LSU nuclear rDNA in spores placed G. aurantium sequences in the G. versiforme group, while G. xanthium sequences were aligned with those in Glomus Group A.
