Algovoracomycetes Tedersoo & Y. Ding class. nov.

Type order.

Algovoracales Tedersoo & Y. Ding .

Diagnosis.

Distinguishable from other fungi based on a diagnostic nucleotide signature in SSU V 5 (positions 696–714 in S. cerevisiae tctttctttctggggaacc or ycttttcttttggggaacc; no mismatch allowed). Forms a monophyletic, least inclusive clade in Monoblepharomycota, covering sequences MF 163176 , OQ 702880, EF 024210, OQ 687303, OQ 687304, OQ 687305, OQ 687310, OQ 687311, EUK 1216850 , DQ 244008, UDB 014650 , EUK 1124454 , EUK 1216854 , EUK 1216849 , and OQ 687309 (Fig. 1 ).

Notes.

Encoded as clade GS 13 in EUKARYOME v 1.9. Algovoracomycetes currently harbors Algovoracales (ord. nov.), Solivoracales (ord. nov.), and a potential order-level group represented by the sequence OQ 687304 (lake water in MI, USA). Comprises potentially 130–160 species. Detected in soil (65.0 % out of 303 records), water (20.5 %), sediment (13.2 %), and algae (1.3 %). Algovoracomycetes includes algal parasites, but it remains unknown if this is the most common trophic strategy or characteristic of the order Algovoracales . Members of Algovoracomycetes have been recorded from high arctic to hot tropical biomes across all continents, including Antarctica.

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.
