Parvocarpum Magurno gen. nov.

Type species.

Parvocarpum badium (Oehl, Redecker & Sieverd.) Magurno.

Description.

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. Forms a monophyletic group within Glomeraceae based on SSU- ITS - LSU phylogram (Fig. 1 , Suppl. material 1).

Notes.

Based on ITS and LSU sequences, Parvocarpum includes 10–20 species.

Figure 1. 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.
