Mirabilomycetes Tedersoo & R. H. Nilsson class. nov.

Type order.

Mirabilomycetales Tedersoo & R. H. Nilsson .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in ITS 2 (positions 102–109 cttgaaat in the type species; one mismatch allowed). Forms a monophyletic, least inclusive clade in Mirabilomycota, covering sequences EUK 1100742 , EUK 1204083 , EUK 1200757 , EUK 1201873 , EUK 1211619 , EUK 1200676 , EUK 1201256 , EUK 1203033 , EUK 1201246 , EUK 1201583 , EUK 1107008 , EUK 1110728 , EUK 1109741 , EUK 1201657 , EUK 1109988 , EUK 1108787 , and EUK 1115028 (Fig. 1 ).

Notes.

Recognized based on eDNA sequences only. Currently harbors Mirabilomycetales and potentially order-level groups represented by sequences EUK 1107008 (forest soil in Puerto Rico), EUK 1110728 (forest soil in Sweden), EUK 1109741 (forest soil in Puerto Rico), EUK 1201657 (forest soil in Estonia), EUK 1109988 (forest soil in Puerto Rico), EUK 1108787 (cropland soil in Great Britain), and EUK 1115028 (unspecified soil in Tibet).

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.
