Waitukubulimyces Tedersoo gen. nov.

Type species.

Waitukubulimyces cliftonii Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in LSU 5 ’ end (positions 52–66 in type species and S. cerevisiae tggaggaaaagaaaa, no mismatch allowed), LSU D 2 (positions 246–262 in type species and 240–256 in S. cerevisiae tgtgttcrctctgtgat; one mismatch allowed), and ITS 2 (positions 129–138 in type species tgggtcactt; one mismatch allowed). Forms a monophyletic, least inclusive clade in Waitukubulimycetaceae, covering sequences EUK 1120710 , EUK 1173015 , EUK 1186290 , EUK 1186291 , and EUK 1186292 (Figs 1 , 59 ).

Notes.

Recognized based on eDNA sequences only. Comprises five potential species represented by sequences EUK 1120710 (botanical garden soil in Estonia), EUK 1173015 (forest soil in China), and EUK 1186290 and EUK 1186292 (both forest soil in Puerto Rico).

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.

Maximum Likelihood SSU- ITS - LSU phylogram indicating the position of Waitukubulimyces cliftonii within Waitukubulimycota, with ultra-rapid bootstrap values indicated (for higher-level classifications only). Other genus-level groups are collapsed. Aldinomycota spp. were used as an outgroup.
