Cantoromastigaceae Tedersoo fam. nov.

Type genus.

Cantoromastix Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in 5.8S (positions 117–136 in type species and S. cerevisiae ctttcgggtaayccccggga; one mismatch allowed) and ITS 2 (positions 156–170 in type species cgtaaccaaaaggct or cgtaccaratctttt; one mismatch allowed). Forms a monophyletic, least inclusive clade in Cantoromastigales, covering sequences EUK 1124338, EUK 0136917, EUK 0017791, and EUK 0523855 (Fig. 1).

Notes.

Recognized based on eDNA sequences only. Includes Cantoromastix (gen. nov.) and another potentially genus-level group represented by the sequence EUK 0523855 (forest soil in FL, USA).
