Sumavosporidium Tedersoo & Esmaeilzadeh-Salestani gen. nov.

Type species.

Sumavosporidium sylvestre Tedersoo & Esmaeilzadeh-Salestani .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in 5.8S (positions 124–138 in the type species and 125–139 in S. cerevisiae gcaatcygcaggcat; one mismatch allowed). Forms a monophyletic, least inclusive clade in Sumavosporidiaceae, covering sequences UDB 029033 , UDB 029043 , UDB 029027 , UDB 028954 , and EUK 1104656 (Figs 1 , 45 ).

Notes.

Recognized based on eDNA sequences only. Comprises potentially 160–180 species represented by sequences UDB 029043 (forest soil in Argentina), UDB 028927 ( woodland soil in Greece), UDB 029030 (forest soil in Scotland), EUK 1104656 (forest soil in Sweden), EUK 0481687 (grassland soil in Norway), EUK 1106151 (peatland soil in Sweden), UDB 028954 (forest soil in Argentina), EUK 0481807 (forest soil in Argentina), EUK 0022003 (forest soil in OR, USA), EUK 0481723 (forest soil in Magadan, Russian Federation), and EUK 0481554 (forest soil in Chukotka, Russian Federation).

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. Rozellomycota spp. were used as an outgroup.
