abstract = {In this study we reassess the taxonomic reference of the previously described holomorphic alkaliphilic
fungus Heleococcum alkalinum isolated from soda soils in Russia, Mongolia and Tanzania. We show that it is not
an actual member of the genus Heleococcum (order Hypocreales) as stated before and should, therefore, be excluded
from it and renamed. Multi-locus gene phylogeny analyses (based on nuclear ITS, 5.8S rDNA, 28S rDNA,
18S rDNA, RPB2 and TEF1-alpha) have displayed this fungus as a new taxon at the genus level within the family
Plectosphaerellaceae, Hypocreomycetidae, Ascomycota. The reference species of actual Heleococcum members
showed clear divergence from the strongly supported Heleococcum alkalinum position within the Plectosphaerellaceae,
sister to the family Glomerellaceae. Eighteen strains isolated from soda lakes around the world show
remarkable genetic similarity promoting speculations on their possible evolution in harsh alkaline environments. We
established the pH growth optimum of this alkaliphilic fungus at c. pH 10 and tested growth on 30 carbon sources at
pH 7 and 10. The new genus and species, Sodiomyces alkalinus gen. nov. comb. nov., is the second holomorphic
fungus known within the family, the first one being Plectosphaerella ? some members of this genus are known to
be alkalitolerant. We propose the Plectosphaerellaceae family to be the source of alkaliphilic filamentous fungi as
also the species known as Acremonium alcalophilum belongs to this group.}
