Curlevskiomycetes Tedersoo class. nov.

Type order.

Curlevskiales Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in LSU D 2 (positions 549–559 in type species and 494–504 in S. cerevisiae tcagcgtcagc; one mismatch allowed). Forms a monophyletic, least inclusive clade in Curlevskiomycota, covering sequences EUK 1103826 , EUK 1103868 , EUK 1700102 , EUK 1603989 , EUK 1603990 , KF 849654, EUK 1103703 , EUK 1603986 , EUK 1602443 , EUK 1603988 , EUK 1124409 , and EUK 1630897 (Fig. 1 ).

Notes.

Recognized based on eDNA sequences only. Currently harbors Curlevskiales (ord. nov.) and potentially 1–2 order-level groups represented by sequences EUK 1103826 (forest soil in Puerto Rico) and EUK 1700078 (forest soil in Gabon).

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.
