Parakickxellaceae Tedersoo fam. nov.

Type genus.

Parakickxella Tedersoo .

Diagnosis.

Separation from other fungi based on a diagnostic nucleotide signature in 5.8S (positions 117–126 in the type species and 120–129 in S. cerevisiae tggattactc; one mismatch allowed). Forms a monophyletic, least inclusive clade in Parakickxellales, covering sequences EUK 1700155, EUK 1189325, EUK 1189316, and EUK 1189321 (Fig. 1).

Notes.

Recognized based on eDNA sequences only. Includes Parakickxella (gen. nov.) and another potentially genus-level group represented by the sequence EUK 1700155 (forest soil in Georgia).
