The morphological spore characteristics and their subcellular structures were described from a specimen mounted in: polyvinyl alcohol-lactic acid-glycerine (PVLG) (Koske and Tessier, 1983); a mixture of PVLG and Melzer’s reagent (Brundrett et al., 1994) a mixture of lactic acid to water at 1:1; Melzer’s reagent; and water (Spain, 1990). For identification of the AM fungi species, spores were then examined using a compound microscope at up to 400- fold magnification as described for glomeromycotean classification (Oehl et al., 2011).
