Ruua Tedersoo gen. nov.

Type species.

Ruua coralieae Tedersoo.

Description.

Covers the monophyletic group in Ruuaceae (Fig. 2 ). Phylogenetically delimited as the least inclusive clade covering sequence accessions EUK 1603424, EUK 1600239, EUK 1600169 and EUK 1600180 (Suppl. material 3).

Notes.

Based on ITS and LSU sequences, Ruua is comprised of 3–4 potential species that are represented by sequences EUK 1632165 (GSMc plot S 510, village habitat soil in Kihnu, Estonia, 58.1282 ° N, 23.9815 ° E); EUK 1603289 (GSMc plot G 4450, Fraxinus - Tilia forest soil in Nigula, Estonia, 58.0190 ° N, 24.6803 ° E); EUK 1103406 (freshwater in Skogaryd, Sweden, 58.37 ° N, 12.16 ° E); and FN 610984 ( Fagus sylvatica forest soil in Breuil-Chenue, France, 47.301 ° N, 4.076 ° E), isolated by Coralie Damon ( Damon et al. 2010).

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.
