Additions to hyphomycetes from Yungui Plateau, China with three new species (Ascomycota, Sordariomycetes).

Background: Yungui Plateau is rich in fungal diversity. Hyphomycetes, growing on submerged wood, can promote the degradation of organisms and the reuse of rotten wood energy. During an investigation of hyphomycetes in this region, 19 species of dematiaceous hyphomycetes were collected in Yungui Plateau.

Diversity, morphology, and molecular phylogeny of from southern China.

During an investigation of from southern China, 10 xylariales-like taxa have been collected. Morphological and multi-gene analyses confirmed that these taxa reside in and represent eight novel taxa and two new records belonging to six genera ., , and gen.

First-Principles Study on Mechanical and Optical Behavior of Plutonium Oxide under Typical Structural Phases and Vacancy Defects.

The chemical corrosion aging of plutonium is a very important topic. It is easy to be corroded and produces oxidation products of various valence states because of its 5f electron orbit between local and non-local. On the one hand, the phase diagram of plutonium and oxygen is complex, so there is still not enough research on typical structural phases.

A taxonomic study of from China, with six new species.

During an investigation of Xylariaceae from 2019 to 2020, isolates representing eight (Xylariacese) species were collected from Yunnan, Guizhou and Hainan Provinces in China. Morphological and multi-gene phylogenetic analyses, based on combined ITS, α-actin, and β-tubulin sequences, confirmed that six of them are new to science, viz. , , , , and ; one is a new record () for China and one is a known species ().
