Aspergillus section Restricti together with sister section Aspergillus (formerly Eurotium) comprises xerophilic species, that are able to grow on substrates with low water activity and in extreme environments. We adressed the monophyly of both sections within subgenus Aspergillus and applied a multidisciplinary approach for definition of species boundaries in sect. Restricti. The monophyly of s...

We describe and illustrate two new species of Boletellus section Boletellus, B. aurocontextus sp. nov. and B. areolatus sp. nov., which are generally assumed to be B. emodensis. In this study, we reconstructed separate molecular phylogenetic trees of section Boletellus using the nucleotide sequences of the internal transcribed spacer (ITS) region of nuclear ribosomal DNA, the largest subunit (R...

Three novel species collected from Dinghushan Biosphere Reserve (DHSBR) in southern China, Russula cylindrica Y.Song sp. nov. and R. lacteocarpa subgenus Archaeae reticulofolia subg. Compactae, are described based on morphological molecular data. In addition, leucobrunnea nom. is proposed replacement of leucocarpa illeg. Brevipedum, as (T.Lebel) T.Lebel had been earlier. Differences between the...

Powdery mildews are a group of economically and ecologically important plant pathogens. In the past 25 years use ribosomal DNA (rDNA) in powdery has led to major taxonomic revisions. However, broad scale rDNA also revealed multiple species complexes that cannot be differentiated based on ITS + LSU data alone. Currently, there only two mildew studies took multi-locus approach resolve complex. pr...

The family Dermateaceae belongs to the Helotiales order, class Leotiomycetes, and consists of 14 genera. In this study, we introduce new genus Pseudoxenochalara gen. nov. family, which is supported by morphological observations multilocus phylogenetic analysis. Partial sequences loci encoding ?-tubulin (BenA), ribosomal polymerase II second largest subunit (RPB2), 28S rDNA (LSU) internal transc...

Two new species, Russula pseudopunicea C.L.Hou, G.Q.Cheng & H.Zhou sp. nov. and R. wulingshanensis nov., from Yanshan mountains in North China are described herein based on morphological phylogenetic analyses of nrITS, nrLSU-rpb2-mtSSU gene regions. Morphologically, is characterised by a reddish brown, light brown to brownish orange pileus with greyish yellow margin, subglobose broadly elli...

Dictyophora rubrovolvata is an important edible mushroom that widely cultivated in China. In 2019, a serious rot disease on D. was observed production facility located Ce Heng County, Southwest of Guizhou Province, The causal agent identified as Trichoderma koningiopsis by amplification and sequencing the internal transcribed spacer (ITS) region, translation elongation factor 1-alpha (EF-1?) ge...

The flap domain of multisubunit RNA polymerases (RNAPs), also called the wall, forms one side of the RNA exit channel. In bacterial RNAP, the mobile part of the flap is called the flap tip and makes essential contacts with initiation and elongation factors. Cocrystal structures suggest that the orthologous part of eukaryotic RNAPII, called the flap loop, contacts transcription factor IIB (TFIIB...
