Paraspizellomyces Tedersoo gen. nov.

Type species.

Paraspizellomyces parrentiae Tedersoo .

Diagnosis.

Distinguishable from other fungi based on diagnostic nucleotide signatures in LSU D 1 (positions 228–237 in type species and 227–236 in S. cerevisiae taacgaccca; one mismatch allowed) and SSU V 9 (positions 1695–1709 in S. cerevisiae aatttcggttgctgg or agtttcggccgctgg; one mismatch allowed). Forms a monophyletic, least inclusive clade in Paraspizellomycetaceae, covering sequences EUK 1187441 , EUK 1187447 , UDB 014658 , and EUK 1100628 (Figs 1 , 4 ).

Notes.

Recognized based on eDNA sequences only. Comprises potentially 20–30 species represented by sequences EUK 1187447 (forest soil in Puerto Rico), UDB 014658 (forest soil in Madagascar), EUK 1100628 (forest soil in Puerto Rico), and GQ 921827 (forest soil in Australia).

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.

Figure 4. Maximum Likelihood SSU- ITS - LSU phylogram indicating the position of Paraspizellomyces parrentiae within Paraspizellomycetales, with ultra-rapid bootstrap values indicated (for higher-level classifications mainly). Other genus-level groups are collapsed. Chytridiomycota spp. were used as an outgroup.
