Mirabilomycetales Tedersoo & R. H. Nilsson

Type family.

Mirabilomycetaceae Tedersoo & R. H. Nilsson .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in the LSU 5 ’ end (positions 1–11 in the type species and S. cerevisiae tcattctcaac or cggatctcaaa; one mismatch allowed). Forms a monophyletic, least inclusive clade in Mirabilomycetes, covering sequences EUK 1100742 , EUK 1204083 , EUK 1200757 , EUK 1201873 , EUK 1211619 , EUK 1200676 , EUK 1201256 , EUK 1203033 , EUK 1201246 , and EUK 1201583 (Fig. 1 ).

Notes.

Recognized based on eDNA sequences only. Currently includes Mirabilomycetaceae (fam. nov.) and other potentially family-level groups represented by sequences EUK 1100742 (unspecified soil in Tibet), EUK 1204083 (tundra soil in Norway), EUK 1200757 (grassland soil in Italy), EUK 1201873 (forest soil in Estonia), and EUK 1211619 (grassland soil in Italy).

Figures

Figure 1. Maximum Likelihood SSU- 5.8 S-LSU phylogram indicating placement of novel lineages in the fungal kingdom as highlighted in a coloured shade and red font. Previously described taxonomic clades are collapsed. All branches of Sumavosporidiomycetes and Gelotisporidiomycetes are shortened two-fold. Poorly supported branches with bootstrap values below 95 % / 99 % are indicated in blue. The original tree with bootstrap values and uncollapsed branches is indicated in Suppl. material 1.
