Type species.

Lokrumastenii Tedersoo.

Description.

Covers the monophyletic group in Lokrumaceae (Fig. 2). Phylogenetically delimited as the least inclusive clade covering sequence accessions EUK1203766, EUK1600125 and EUK1600078 (Suppl. material 3).

Notes.

Based on ITS sequences, Lokruma is comprised of 35–40 species, some of which are represented by sequences EUK1200048 (GSMc plot G5130, grassland soil in Angera, Italy, 45.77336°N, 8.59657°E); EUK1602967 (GSMc plot G4626, Picea-Populus forest soil in Kõrve, Estonia, 59.07754°N, 26.76144°E); and EUK1603058 (Piceaabies forest soil in Serga, Estonia, 57.76052°N, 27.47502°E). Given the relatively high intraspecific differences and low interspecific differences, the LSU region is not optimal for distinguishing species of Lokruma.

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.
