Waitukubulimycota Tedersoo phyl. nov.

Type class.

Waitukubulimycetes Tedersoo.

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in the LSU 5 ’ end (positions 52–66 in the type species and S. cerevisiae tggaggaaaagaaaa, no mismatch allowed). Forms a monophyletic, least inclusive clade in fungi, covering sequences EUK 1120710 , EUK 1173015 , EUK 1186290 , EUK 1186291 , and EUK 1186292 (Fig. 1 ).

Notes.

Recognized based on eDNA sequences only. Not encoded specifically in EUKARYOME v 1.9. Waitukubulimycota currently harbors the single class Waitukubulimycetes. Waitukubulimycota comprises five species. Members of this phylum have been detected in soil (100 % out of seven records) in arctic to wet tropical biomes across all continents, excluding 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.
