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.
