Mirabilomycetaceae Tedersoo & R. H. Nilsson fam. nov.

Type genus.

Mirabilomyces Tedersoo & R. H. Nilsson .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in the LSU 5 ’ end (positions 1–11 in the type species and S. cerevisiae tcattctcaac; one mismatch allowed) and ITS 2 (positions 196–208 in type species aacaatgacttga; one mismatch allowed). Forms a monophyletic, least inclusive clade in Mirabilomycetales, covering sequences EUK 1200676, EUK 1201256, EUK 1203033, EUK 1201246, EUK 1201583, EUK 1201728, and EUK 1124366 (Fig. 1).

Notes.

Recognized based on eDNA sequences only. Includes Mirabilomyces (gen. nov.) and other potentially genus-level groups represented by sequences EUK 1201256 (grassland soil in Switzerland), EUK 1203033 (forest soil in the Canary Islands), EUK 1201246 (forest soil in Estonia), and EUK 1201583 (grassland soil in Norway).
