Description.

Densosporales is defined as a monophyletic group in Endogonomycetes (Fig. 2, Suppl. material 3) that corresponds to Densosporaceae sensu Desiro et al. (2017). Covers Densosporacae and Planticonsortiaceae and the least inclusive clade with sequence accessions UDB028692, EUK1104889, EUK1104816 and EUK1601509 (Suppl. material 3).

Notes.

Densosporales harbours roughly one half of the Endogonomycetes based on LSU data. It comprises Densosporacae, Planticonsortiaceae and 16 additional family-level groups collectively covering >200 species. LSU has much greater phylogenetic resolution compared with SSU (Suppl. materials 3, 4), and the potential utility of the ITS region seems to vary greatly by family. Many more ITS-LSU sequences are needed to understand family- and genus-level composition of Densosporales.

Phylogenetic position of genera and genus-level groups of Endogonomycetes based on Maximum Likelihood analysis of SSU-5.8S-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. The uncollapsed phylogram is given in Suppl. material 3.
