Lokruma Tedersoo gen. nov.

Type species.

Lokruma stenii Tedersoo.

Description.

Covers the monophyletic group in Lokrumaceae (Fig. 2 ). Phylogenetically delimited as the least inclusive clade covering sequence accessions EUK 1203766, EUK 1600125 and EUK 1600078 (Suppl. material 3).

Notes.

Based on ITS sequences, Lokruma is comprised of 35–40 species, some of which are represented by sequences EUK 1200048 (GSMc plot G 5130, grassland soil in Angera, Italy, 45.77336 ° N, 8.59657 ° E); EUK 1602967 (GSMc plot G 4626, Picea - Populus forest soil in Kõrve, Estonia, 59.07754 ° N, 26.76144 ° E); and EUK 1603058 ( Picea abies 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 .

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.
