Langduoa Tedersoo gen. nov.

Type species.

Langduoa dianae Tedersoo.

Description.

Covers the monophyletic group in Langduoaceae (Fig. 2 ). Phylogenetically delimited as the least inclusive clade covering sequence accessions EUK 1107335, EUK 1103607 and EUK 1632829 (Suppl. material 3).

Notes.

Based on ITS sequences, Langduoa is comprised of 40–50 species. The genus is distributed globally in multiple habitat types, but not found from roots so far. Most Langduoa species are poorly separable based on the LSU marker. Other putative species in Langduoa are represented by sequences EUK 1103607 (tropical rainforest soil in El Yunque, Puerto Rico, 18.29 ° N, - 65.78 ° E); EUK 1631446 (GSMc plot G 4189, Populus tremula forest soil in Tammsaare, Estonia, 57.84444 ° N, 27.20141 ° E); and MW 215048 (tree nursery soil in Lithuania), which was recorded by Diana Marčiulynienė ( Marčiulynienė et al. 2021).

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.
