ord. nov.

Type family.

Riederbergaceae Tedersoo.

Description.

Covers the monophyletic group in Endogonomycetes (Fig. 2). Phylogenetically delimited as the least inclusive clade covering sequence accessions EUK1602903, EUK1603115, EUK1602258, EUK1602253, EUK1602251 and EUK1104709 (Suppl. material 3).

Notes.

Recognised based on eDNA sequences only. Currently includes Riederbergaceae and four additional potentially family-level taxa represented by sequences EUK1100540 (bog peat soil in Svartberget, Sweden, 64.24°N, 19.76°E); EUK1602254 (GSMc plot G5826, Malusdomestica orchard in Tabivere, Estonia, 58.54286°N, 26.61575°E); EUK1602251, EUK1602253 and EUK1602257 (all GSMc plot G5828, Estonia, Malusdomestica orchard soil in Mooste, Estonia, 58.15335°N, 27.19642°E). Sequences EUK0031975 (GSMc plot S1082, Araucariaaraucana forest, Nahuelbuta, Chile, -37.78985°N, -73.0038°E) and EUK1217433 (GSMc plot G4777, maritime grassland (saltmarsh) soil in Härs-hämani, Estonia, 59.33103°N, 23.92720°E) represent additional, monospecific, potentially family-level groups not included in the phylograms due to the lack of LSU sequences.

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.
