See Spain and Miranda (1996).

Diagnosis.

Fuscutatacerradensis differs from other species of the Fuscutata by spore wall ornamentation, three-walled spores and dark-pigmented multilobed germinal shield produced in the inner wall. Phylogenetically forms a monophyletic clade with F.heterogama - the type species of genus - based on the SSU-ITS-LSU phylogram (Fig. 1, Suppl. material 1).

Notes.

The new combination invites an amendment of genus Fuscutata to accommodate species with dark, multilobed germinal shields. However, we decided not to prepare an amendment for Fuscutata because the genus Dentiscutata, their close relative, requires additional information to confirm their status, supported only in the LSU sequence of D.nigra.

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.
