The inner layer of gw2 (L2) is described for A. morrowiae as producing a “light purple” reaction in Melzer’s reagent (Schenck et al, 1984), but mounted type specimens as well as those stored in lactophenol and then mounted in Melzer’s reagent both showed a dark red-purple reaction similar to that observed by this reference isolate.Description: All known species produce spores without ornamentations. Spores consist of only a bilayered spore wall; germ tubes arise from a thin papillate (warty) layer arising from inner surface the laminate layer. Thin-walled auxiliary cells with echinulate surfaces, are produced on hyphae in the soil near the root surface. Type species:In the plant compartment, the sand mix was inoculated with 26 g of whole inoculum of R. intraradices (accession number AZ243, International Culture Collection of (Vesicular) Arbuscular Mycorrhizal Fungi (INVAM), West Virginia University, Morgantown, WV, USA).
