Abstract

Paraglomus majewskii sp. nov. (Glomeromycota) is described and illustrated. It forms single spores, which are hyaline through their entire life cycle, globose to subglobose, (35‒)63(‒78) µm diam, sometimes egg-shaped, 50‒70 × 65‒90 µm, and have an unusually narrow, (3.2‒)4.6(‒5.9) µm wide, cylindrical to slightly flared subtending hypha. The spore wall of P. majewskii consists of an evanescent, short-lived outermost layer, a laminate middle layer, and a flexible innermost layer, which adheres tightly to the middle layer. None of the spore wall layers stain in Melzer's reagent. In single-species cultures with Plantago lanceolata as the host plant, P. majewskii, formed arbuscular mycorrhizae staining violet in trypan blue. P. majewskii has been isolated from several, distant geographic regions, and from different habitats. In phylogenetic analyses of partial nrDNA SSU and LSU sequences the fungus formed a monophyletic group with Paraglomus species, however it represents a well-separated distinct lineage. Its nrDNA sequences are highly similar to in planta arbuscular mycorrhizal fungal sequences from different habitats in Spain and Ecuador.
