Both species formed spores in loose clusters and singly in soil, and G. iranicum sometimes inside roots. Spores of G. africanum are pale yellow to brownish yellow, globose to subglobose, (60‒)87(‒125) ?m diam., sometimes ovoid to irregular, 80‒110 ? 90‒140 ?m. Their spore wall consists of a semi-permanent, hyaline, outer layer and a laminate, smooth, pale yellow to brownish yellow, inner layer, which always is markedly thinner than the outer layer. Spores of G. iranicum are hyaline to pastel yellow, globose to subglobose, (13‒)40(‒56) ?m diam., rarely egg-shaped, prolate to irregular, 39‒54 ? 48‒65 ?m. The spore wall consists of three smooth layers: a mucilaginous, short-lived, hyaline outermost layer, a permanent, semi-rigid, hyaline middle layer, and a laminate, hyaline to pastel yellow innermost layer. Only the outermost spore wall layer of G. iranicum stains red in Melzer's reagent. In the field, G. africanum was associated with roots of five plant species and an unrecognized shrub colonizing maritime sand dunes of two countries of Europe and two of Africa, and G. iranicum was associated with Triticum aestivum cultivated in southwestern Iran. In one-species cultures with Plantago lanceolata as the host plant, G. africanum and G. iranicum formed arbuscular mycorrhizae. Phylogenetic analyses of partial SSU sequences of nrDNA placed the two new species in Glomus group A. Both species were distinctly separated from sequences of described Glomus species.} }
