Type species.

Riederbergasylviae Tedersoo.

Description.

Covers the monophyletic group in Riederbergaceae (Fig. 2). Phylogenetically delimited as the least inclusive clade covering sequence accessions EUK1602903, EUK1602242 and EUK1602243 (Suppl. material 3).

Notes.

Based on ITS and LSU sequences, Riederberga is comprised of 5–6 species, some of which are represented by sequences EUK1602859 (GSMc plot G4770, Populusberolinensis dominated coppiced garden in Ubasalu, Estonia, 59.06755°N, 24.47842°E); EUK1602912 (GSMc plot G4772, Juniperuscommunis calcareous woodland soil in Kohatu, Estonia, 58.95934°N, 24.30017°E); EUK1602761 (GSMc plot G4434, mixed woodland soil in Kalli, Estonia, 58.53770°N, 24.06659°E); and EUK1603687 (GSMc plot G4229, Quercusrobur woodland soil in Niidiaia, Estonia, 58.88603°N, 24.47280°E).

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.
