Paraspizellomycetaceae Tedersoo fam. nov.

Type genus.

Paraspizellomyces Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in LSU D 2 (positions 578–592 in type species and 562–576 in S. cerevisiae aaggtcatgcttt; one mismatch allowed) and ITS 2 (positions 134–148 in type species aatggttcccaagtg; two mismatches allowed). Forms a monophyletic, least inclusive clade in Paraspizellomycetales, covering sequences EUK 1187441, EUK 1187447, UDB 014658, EUK 1100628, EUK 1123745, and EUK 1139262 (Fig. 1).

Notes.

Recognized based on eDNA sequences only. Includes Paraspizellomyces (gen. nov.) and another potentially genus-level group represented by sequences EUK 1123745 (forest soil in Estonia), and EUK 1139262 (forest soil in New Zealand).
