Parvocarpum badium (Oehl, Redecker & Sieverd.) Magurno comb. nov. Glomus badium Oehl, D. Redecker & Sieverd., Angew. Botan. 79: 39 (2005). Basionym. Funneliformis badius (Oehl, Redecker & Sieverd.) C. Walker & A. Schüssler. Synonymy. \ Description. See Oehl et al. (2005). Etymology. parvus (Latin) = small; and carpum (Latin) = body, referring to the small size of fruiting bodies produced. Diagnosis. P. badium differs from other genera of the Glomeraceae by producing glomoid-like spores surrounding a central plexus of interwoven hyphae in small organised fruiting bodies, lacking a peridium. Spores with inner flexible hyaline layer and short subtending hyphae. Phylogenetically distinct from G. macrocarpum and other Glomus sens. str. species based on the SSU- ITS - LSU phylogram (Fig. 1, Suppl. material 1). Notes. Phylogenetic position of P. badium within the genus Parvocarpum is unresolved because of a single available short read.
