An in-depth study of the phylogenetic relationships of species associated with nutshells of fruits and seeds within the genus and related genera of Xylaceaecea was conducted in China. The multi-gene phylogenetic analyses were carried out based on ITS, RPB2, and TUB sequences of 100 species of 16 known genera in Xylariaceae around the world. Based on molecular phylogenetic analyses, morphological observations, and ecological habitats, a new genus, , is established to accommodate four new species, viz.

During the investigation of macro-fungi in Motuo county, Tibet Autonomous Region, we collected a number of xylarialean specimens. Six hypoxylaceous specimens growing on dead angiosperm were collected from the forests of Motuo county, and they were described and illustrated as two new species in based on a combination of morphological characters and molecular evidence.

The phylogenetic analyses were carried out based on ITS and β-tubulin sequences of 75 taxa of Diatrypaceae from around the world. Based on a combination of morphological features and molecular evidence, a new genus-, with three new species-, , and , and a new combination-, were revealed by the materials in China.
