Borikeniales Tedersoo ord. nov.

Type family.

Borikeniaceae Tedersoo .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in LSU D 3 (positions 956–967 in type species and 761–772 in S. cerevisiae tcaatttattga OR ggaatttattcc; no mismatch allowed). Forms a monophyletic, least inclusive clade in Borikeniomycetes, covering sequences EUK 1105319, EUK 1189257, EUK 0530094, EUK 0530090, EUK 1189254, EUK 1189255, and EUK 1189256 (Fig. 1).

Notes.

Recognized based on eDNA sequences only. Currently includes Borikeniaceae (fam. nov.) and potentially a family-level group represented by sequences EUK 1189257 (forest soil in Dominica) and EUK 1105319 (forest soil in Puerto Rico).
