Abstract
The family Dermateaceae belongs to the Helotiales order, the class
Leotiomycetes, and consists of 14 genera. In this study, we introduce the
new genus Pseudoxenochalara gen. nov. to the Dermateaceae family, which is
supported by morphological observations and multilocus phylogenetic
analysis. Partial sequences of the loci encoding ?-tubulin (BenA), ribosomal
polymerase II second largest subunit (RPB2), 28S rDNA (LSU) and internal
transcribed spacer rDNA region (ITS1-5.8S-ITS2) were analysed. This genus
comprises one new species, P. grumantiana, isolated from the soil of the
Arctic tundra near the settlement of Barentsburg (the Svalbard archipelago).
The asexual morph of P. grumantiana was described. The sequences data, as
well as the macroand micromorphological characteristics distinguish P.
grumantiana from all known species in the Dermateaceae family.
