Dobrisimastigomycetes Tedersoo class. nov.

Type order.

Dobrisimastigales Tedersoo .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in LSU D 1 (positions 124–138 in the type species and 122–136 in S. cerevisiae tgggtaggttacctg; three mismatches allowed). Forms a monophyletic, least inclusive clade in Neocallimastigomycota, covering sequences EUK 1189296 , EUK 1138904 , EUK 0534669 , EUK 0534670 , and EUK 0534680 (Fig. 1 ).

Notes.

Recognized based on eDNA sequences only. Labelled as clade GS 93 B in EUKARYOME v 1.9. Currently harbors Dobrisimastigales (ord. nov.). Comprises 10–12 species. Detected in soil (91.7 % out of 36 records) and sediments (8.3 %) in tundra to tropical biomes across all continents except Antarctica.

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.
