Gelotisporidiaceae Tedersoo fam. nov.

Type genus.

Gelotisporidium Tedersoo .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in LSU D 2 (positions 613–627 in type species and 692–696 in S. cerevisiae cccttgggcgcaaag; one mismatch allowed). Forms a monophyletic, least inclusive clade in Gelotisporidiales, covering sequences EUK 1138568, EUK 1138757, EUK 1100418, EUK 1138778, EUK 1202629, EUK 1201985, EUK 1104844, EUK 1101158, and EUK 1123671 (Fig. 1).

Notes.

Recognized based on eDNA sequences only. Includes Gelotisporidium and several genus-level groups represented by sequences EUK 1138568 (forest soil in New Zealand), EUK 1138757 (forest soil in New Zealand), EUK 1100418 (permafrost in Canada), EUK 1138778 (forest soil in New Zealand), EUK 1202629 (forest soil in Finland), and EUK 1123671 (forest soil in Estonia).
