Mycosocceria Tedersoo, Bahram & Esmaeilzadeh-Salestani gen. nov.

Type species.

Mycosocceria estonica Tedersoo, Bahram & Esmaeilzadeh-Salestani .

Diagnosis.

Distinguishable from other species of fungi based on diagnostic nucleotide signatures in 5.8S (positions 120–129 in type species and S. cerevisiae cccggtaggc). Forms a monophyletic, least inclusive clade in Mycosocceriaceae, covering sequences EUK 1008618 , EUK 0531631 , and EUK 1124462 (Figs 1 , 31 ).

Notes.

Recognized based on eDNA sequences only. Includes M. estonica and another species represented by sequence EUK 0531631 (savanna soil in Uganda).

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.

Maximum Likelihood SSU- ITS - LSU phylogram indicating the position of Mycosocceria estonica within Mycosocceriales, with ultra-rapid bootstrap values indicated (for higher-level classifications mainly). Other genus-level groups are collapsed. Mortierellomycota spp. were used as an outgroup.
