Riederbergales Tedersoo 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 EUK 1602903, EUK 1603115, EUK 1602258, EUK 1602253, EUK 1602251 and EUK 1104709 (Suppl. material 3).

Notes.

Recognised based on eDNA sequences only. Currently includes Riederbergaceae and four additional potentially family-level taxa represented by sequences EUK 1100540 (bog peat soil in Svartberget, Sweden, 64.24 ° N, 19.76 ° E); EUK 1602254 (GSMc plot G 5826, Malus domestica orchard in Tabivere, Estonia, 58.54286 ° N, 26.61575 ° E); EUK 1602251, EUK 1602253 and EUK 1602257 (all GSMc plot G 5828, Estonia, Malus domestica orchard soil in Mooste, Estonia, 58.15335 ° N, 27.19642 ° E). Sequences EUK 0031975 (GSMc plot S 1082, Araucaria araucana forest, Nahuelbuta, Chile, - 37.78985 ° N, - 73.0038 ° E) and EUK 1217433 (GSMc plot G 4777, 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.

Figures

Figure 2. Phylogenetic position of genera and genus-level groups of Endogonomycetes based on Maximum Likelihood analysis of SSU- 5.8 S-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.
