Curlevskia Tedersoo gen. nov.

Type species.

Curlevskia holarctica Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in ITS 2 (positions 88–97 in type species tcgcgaatcc; one mismatch allowed) and LSU D 2 (positions 565–574 in type species and 509–518 in S. cerevisiae atcgcgggaa; one mismatch allowed). Forms a monophyletic, least inclusive clade in Curlevskiaceae, covering sequences EUK 1603989, EUK 1603990, KF 849654, EUK 1103703, EUK 1603986, EUK 1602443, EUK 1603988, EUK 1124409, and EUK 1630897 (Figs 1, 29).

Notes.

Recognized based on eDNA sequences only. Comprises 40–60 species represented by sequences EUK 1603985 (wasteland soil in Estonia), EUK 1603986 (cropland soil in Estonia), EUK 1603987 (grassland soil in Estonia), EUK 1603988 (wasteland soil in Estonia), KJ 701460, KJ 701455, and KF 849654 (all from plant roots in China), GU 187865 ( woodland soil in VIC, Australia), and EUK 1103703 (forest soil in Puerto Rico).
