Diversispora clara (Glomeromycetes)— a new species from saline dunes in the Natural Park Cabo de Gata (Spain)
A new species of Diversispora (Glomeromycetes) was found in saline sand dunes of the Natural Park Cabo de Gata (Almería, Andalucía, Southern Spain) in the rhizosphere of Asteriscus maritimus, a plant species especially adapted to saline environments. The new fungal species forms brilliant white spores that are 79–130 × 75–125 μm and have one wall consisting of three layers. The subtending hyphae are, as typical for many Diversispora spp., thin-walled, hyaline, and cylindrical (or rarely constricted) and flexible and fragile below the septa separating the spore and hyphal contents. The septa form regularly at the spore bases or, less frequently, in subtending hyphae at short distances from the spore base. Phylogenetic analyses of the ITS and partial 28S ribosomal gene confirm that D. clara forms a monophyletic, independent clade within Diversispora.
