Bryolpidium Tedersoo gen. nov.

Type species.

Bryolpidium mundanum Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in SSU V 9 (positions 1706–1719 in S. cerevisiae gtcgagaagttatc; one mismatch allowed), ITS 2 (positions 102–113 in type species agngaacagcgg; one mismatch allowed), and LSU D 1 (positions 169–183 in type species and 167–181 in S. cerevisiae cgcggctgccgaagt; one mismatch allowed). Forms a monophyletic, least inclusive clade in Bryolpidiaceae, covering sequences EUK 1124873 and EUK 1608195 (Figs 1 , 37 ).

Notes.

Recognized based on eDNA sequences only. Comprises 9–10 species represented by sequences EUK 1608195 (forest soil in Morocco), EUK 0044951 (grassland soil in Kyrgyzstan), EUK 0534697 (forest soil in Pakistan), EUK 0045451 (tundra soil in Leonie Island, Antarctica), EUK 0320829 (lake sediment in Germany), EUK 0534698 (grassland soil in Kyrgyzstan), EUK 0574099 (river sediment in Scotland), and EUK 0534695 (forest soil in Turkey).

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. Olpidiomycota spp. were used as an outgroup.
