See Palenzuela et al. (2010).

Diagnosis.

Diversisporanevadensis differs from other species of the Diversispora by producing entrophosporoid (tricisporoid) spores compared with diversisporoid and acaulosporoid (otosporoid) spores in other species. Glomerospores with inner flexible hyaline wall layers without granular beaded surface and no Melzer reaction. Phylogenetically nested in Diversispora based on the SSU-ITS-LSU phylogram (Fig. 1, Suppl. material 1).

Notes.

The new combination invites an amendment of the genus Diversispora to accommodate species with entrophosporoid (tricisporoid) spores.

Phylogenetic position of genera and genus-level groups of Glomeromycota based on Maximum Likelihood analysis of SSU-ITS-LSU sequences. The clades are collapsed, with the number of sequences included in parentheses. Question marks above branches indicate low ultra-rapid bootstrap support (< 95). Orders are highlighted in different colours. For the genus Entrophospora, the so-called S-type reads (VanKuren et al. 2013) were included for comparison. The uncollapsed phylogram is given in Suppl. material 1.
