Lehetua Tedersoo gen. nov.

Type species.

Lehetua indrekii Tedersoo.

Description.

Covers the monophyletic group in Lehetuaceae (Fig. 2 ). Phylogenetically delimited as the least inclusive clade covering sequence accessions EUK 1603180, EUK 1602366 and EUK 1602374 (Suppl. material 3).

Notes.

Based on ITS and LSU sequences, Lehetua is comprised of 8–10 species. Other putative ITS - based species in Lehetua are represented by sequences EUK 1602811 (GSMc plot G 4105, Picea abies forest soil in Lepa, Estonia, 57.70158 ° N, 26.23993 ° E); EUK 1603124 (GSMc plot G 5003, Pinus sylvestris forest soil in Naissaar, Estonia; 59.5634 ° N, 24.5451 ° E); and EUK 0022184 (GSMc plot AV 106, Pseudomonotes tropenbosii rainforest soil in El Zafire, Colombia, - 3.995 ° N, - 69.898 ° E).

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.
