Borikeniaceae Tedersoo fam. nov.

Type genus.

Borikenia Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in LSU D 3 (positions 956–967 in type species and 761–772 in S. cerevisiae tcaatttattga; no mismatch allowed) and 5.8S (positions 130–142 in type species and 132–144 in S. cerevisiae aagagtatttctg; one mismatch allowed). Forms a monophyletic, least inclusive clade in Borikeniales, covering sequences EUK 1189254 , EUK 0530094 , EUK 0530090 , EUK 1189255 , and EUK 1189256 (Fig. 1 ).

Notes.

Recognized based on eDNA sequences only. Includes the genus Borikenia (gen. nov.) and another potential genus-level group represented by sequences EUK 1189255 (forest soil in the British Virgin Islands) and EUK 1189256 (forest soil in Dominica).

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.
