Borikeniaceae Tedersoo fam. nov.

Type genus.

Borikenia Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in LSU D 3 (positions 956–967 in type species and 761–772 in S. cerevisiae tcaatttattga; no mismatch allowed) and 5.8S (positions 130–142 in type species and 132–144 in S. cerevisiae aagagtatttctg; one mismatch allowed). Forms a monophyletic, least inclusive clade in Borikeniales, covering sequences EUK 1189254, EUK 0530094, EUK 0530090, EUK 1189255, and EUK 1189256 (Fig. 1).

Notes.

Recognized based on eDNA sequences only. Includes the genus Borikenia (gen. nov.) and another potential genus-level group represented by sequences EUK 1189255 (forest soil in the British Virgin Islands) and EUK 1189256 (forest soil in Dominica).
