Tartumyceta Tedersoo subreg. nov.

Type phylum.

Tartumycota Tedersoo.

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in LSU D 3 (positions 1009–1023 in type species and 969–983 in S. cerevisiae ggaacttgtacagtt, no mismatch allowed). Forms a monophyletic, least inclusive clade in fungi, covering sequences OQ 702815, EUK 1186161 , OQ 687331, EUK 1186165 , EUK 1186157 , EUK 1200073 , EUK 1186162 , EUK 1123648 , EUK 1138300 , OQ 702816, ON 754309, UDB 028835 , and HQ 191300 (Fig. 1 ).

Notes.

Recognized as a subkingdom due to its sister position to all remaining fungi. Currently harbors Tartumycota (phyl. nov.).

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.
