Ruderalia Tedersoo gen. nov.

Type species.

Ruderalia cosmopolita Tedersoo .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in ITS 2 (positions 209–222 aacgatagtgaagt; two mismatches allowed). Forms a monophyletic, least inclusive clade in Ruderaliaceae, covering sequences EUK 1138161 , EUK 1137899 , EUK 0531800 , and EUK 1124460 (Figs 1 , 35 ).

Notes.

Recognized based on eDNA sequences only. Comprises potentially three species represented by sequences EUK 0531803 (cropland soil in Benin) and EUK 0531800 (forest soil in Ghana).

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.

Other genus-level groups are collapsed. Mortierellomycota spp. were used as an outgroup.
