Aldinomycetales Tedersoo ord. nov.

Type family.

Aldinomycetaceae 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 Aldinomycetes, 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. Currently includes Aldinomycetaceae (fam. nov.) and other potentially family-level groups represented by sequences EUK 1111390 (forest soil in Sweden), EUK 0320466 (river sediment in Spain), EUK 0529888 (orchard soil in Estonia), and EUK 0320468 (river sediment in Spain).

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.
