Bryolpidiomycetes Tedersoo class. nov.

Type order.

Bryolpidiales Tedersoo .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in LSU D 1 (positions 169–183 in the type species and 167–181 in S. cerevisiae cgcggctgccgaagt or ggtcgcgaccgcggt; one mismatch allowed). Forms a monophyletic, least inclusive clade in Olpidiomycota, covering sequences EUK 1124873, EUK 1608195, EUK 1186288, and EUK 1186289 (Fig. 1).

Notes.

Recognized based on eDNA sequences only. Encoded as clade GS 93 G in EUKARYOME v 1.9. Currently harbors Bryolpidiales (ord. nov.) and another potentially order-level group represented by sequences EUK 1186288 and EUK 1186289 (both forest soil in Altay Kray, Russian Federation). Comprises potentially 10–11 species. Detected in soil (88.5 % out of the 26 records) and sediments (11.5 %) in tundra to hot tropical biomes across all continents, including Sub-Antarctic islands.
