Type species.

Lehetuaindrekii Tedersoo.

Description.

Covers the monophyletic group in Lehetuaceae (Fig. 2). Phylogenetically delimited as the least inclusive clade covering sequence accessions EUK1603180, EUK1602366 and EUK1602374 (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 EUK1602811 (GSMc plot G4105, Piceaabies forest soil in Lepa, Estonia, 57.70158°N, 26.23993°E); EUK1603124 (GSMc plot G5003, Pinussylvestris forest soil in Naissaar, Estonia; 59.5634°N, 24.5451°E); and EUK0022184 (GSMc plot AV106, Pseudomonotestropenbosii rainforest soil in El Zafire, Colombia, -3.995°N, -69.898°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.
