Edaphochytriaceae Tedersoo fam. nov.

Type genus.

Edaphochytrium Tedersoo .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in the LSU 5 ’ end (positions 15–24 in the type species and S. cerevisiae tagtggacta or tgatggacta; one mismatch allowed). Forms a monophyletic, least inclusive clade in Edaphochytriales, covering sequences EUK 1008462 , EUK 1200051 , EUK 1123749 , EUK 1630709 , EUK 1123746 , EUK 1200763 , and EUK 1123748 (Fig. 1 ).

Notes.

Recognized based on eDNA sequences only. Includes Edaphochytrium (gen. nov.) and other potentially genus-level groups represented by sequences EUK 1123749 and EUK 1008462 .

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.
