Terrincola Tedersoo & Esmaeilzadeh-Salestani gen. nov.

Type species.

Terrincola waldropii Tedersoo & Esmaeilzadeh-Salestani .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signature in ITS 2 (positions 23–32 ggccgtacgg; one mismatch allowed). Forms a monophyletic, least inclusive clade in Terrincolaceae, covering sequences MW 791967, EUK 0473585 , and EUK 1138132 (Figs 1 , 27 ).

Notes.

Recognized based on eDNA sequences only. Comprises potentially four species represented by sequences EUK 0473585 (shrubland soil in Uyghur Autonomous Region, China), EUK 1604143 (forest soil in VT, USA), and EUK 1604137 (forest soil in South Africa).

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 Terrincola waldropii within Terrincolales with ultra-rapid bootstrap values indicated (for higher-level classifications mainly). Other genus-level groups are collapsed. Calcarisporiellomycetes spp. were used as an outgroup.
