Mirabilomycota Tedersoo & R. H. Nilsson phyl. nov.

Type class.

Mirabilomycetes Tedersoo & R. H. Nilsson.

Diagnosis.

Forms a monophyletic, least inclusive clade in fungi, covering sequences EUK 1101676 , EUK 1107181 , EUK 1103059 , EUK 1100023 , EUK 1103883 , EUK 1102753 , 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. Encoded as clade GS 41 in EUKARYOME v 1.9. There are no diagnostic nucleotide signatures to distinguish them from other fungi due to rapid rRNA gene evolution in certain class- and order-level groups. Currently harbors Mirabilomycetes (class. nov) and potentially class-level groups represented by sequences EUK 1101676 (forest soil in Puerto Rico), EUK 1107181 (forest soil in Puerto Rico), EUK 1103059 (forest soil in Puerto Rico), EUK 1100023 (forest soil in Sweden), EUK 1103883 (forest soil in Puerto Rico), and EUK 1102753 (forest soil in Puerto Rico). Comprises potentially 1500–1800 species. Detected in soil (99.9 % out of 6193 records) and sediments (0.1 %) in tundra to wet tropical biomes across all continents except Antarctica.

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.
