Aldinomycota Tedersoo phyl. nov.

Type class.

Aldinomycetes Tedersoo.

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in SSU V 4 (positions 732–746 gattcaggaccttca in S. cerevisiae ; no mismatch allowed), SSU V 7 (positions 1346–1355 gttgttggtc in S. cerevisiae ; no mismatch allowed), and LSU D 3 (positions 912–926 in the type species and 771–785 in S. cerevisiae : ggttttgagaaaaag; one mismatch allowed). Forms a monophyletic, least inclusive clade in fungi, covering sequences EUK 0320466 , EUK 0529888 , EUK 1205365 , EUK 1124394 , EUK 0529884 , EUK 1111390 , EUK 0529911 , and EUK 0320468 (Fig. 1 ).

Notes.

Recognized based on eDNA sequences only. Encoded as clade GS 45 in EUKARYOME v 1.9. Comprises potentially 65–70 species. Currently harbors Aldinomycetes (class. nov.). Detected in soil (98.2 % out of 113 records) and sediments (1.8 %) in tundra to wet tropical biomes across all continents except Antarctica.

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.
